Cheryl shot to stardom in 2002 as a member of Girls Aloud after winning Popstars: The Rivals. The quintet went on to become one of the biggest-selling girl groups of all time, scoring 20 UK top 10 singles. Cheryl followed that up with a judging role on The X Factor and launched a solo career that spawned hits including Fight for This Love and Promise This.
A true rags-to-riches success story, Cheryl has also been a L'Oréal ambassador and even dabbled in theatre, a far cry from her humble upbringing on a council estate in Newcastle.
Propelled into the public eye in the early noughties on Laguna Beach: The Real Orange County, Lauren Conrad made her mark in reality TV before successfully transitioning into a business mogul. She later starred in the mega-popular spin-off The Hills.
Conrad has since released a fashion line with Kohl's called Paper Crown and co-founded ethical online store The Little Market. She's also a seasoned author with several best-selling novels and beauty books under her belt.
Nicole Richie skyrocketed to fame in 2003 on the hit reality show The Simple Life, where she and her socialite best friend Paris Hilton navigated blue-collar life in hilarious fashion. The daughter of music legend Lionel Richie, she's since established herself as a fashion mogul, having founded her own lifestyle brand House of Harlow, not to mention a reality TV judge, novelist, and actress.
Richie has also stayed in the spotlight thanks to her long-standing marriage to rock star Joel Madden.
Adam Lambert's meteoric rise came in 2009 as the runner-up on the eighth season of American Idol. Lambert's debut album, For Your Entertainment, lit up the charts, producing hit singles like Whataya Want from Me, and he's gone on to release a string of successful albums.
Lambert is also known as the lead singer of Queen + Adam Lambert, and he's gained international acclaim for his powerful performances. The star's career also extends to acting, with notable appearances in prestige TV shows like Glee and Pretty Little Liars.
As Kourtney Kardashian's (now ex) partner, Scott Disick was a regular on Keeping Up with the Kardashians from its 2007 debut and has appeared across its numerous spin-offs. By the mid-2010s, he was reportedly earning $500,000 (£374k) per season.
Beyond the TV franchise, Disick has launched a clothing line called Talentless and starred in Flip It Like Disick, a 2019 series that followed his foray into renovating and flipping luxury properties. He's also “run multiple companies in the vitamin world”, invested in nightclubs, and maintained tabloid visibility through high-profile relationships with Amelia Hamlin and Sofia Richie.
Camille Grammer entered the limelight in 2010 as an original cast member of The Real Housewives of Beverly Hills, where her dramatic first season, which coincided with the breakdown of her marriage to actor Kelsey Grammer, made her one of the show's most talked-about figures.
Before reality TV, she worked as a dancer, model, and producer at Grammnet Productions. Following the divorce, Grammer reportedly secured a settlement worth at least $30 million (£37.5m), forming the backbone of her substantial net worth today.
Catapulted to the big time after winning the very first season of American Idol in 2002, Kelly Clarkson became one of the most successful pop stars of the noughties and 2010s with smash hit singles like Since U Been Gone and Because of You, along with a string of platinum albums.
In recent years, she's moved into TV judging and hosting, which has proven very lucrative indeed. Court filings from her 2021 divorce revealed she was pulling in $1.9 million (£1.4m) a month from The Voice, her namesake talk show, and other revenue streams. All in all, Clarkson is said to have grossed $100 million (£75m) during her long and illustrious career.
The Gaineses have parlayed interior design know-how into serious fame and fortune. As the hosts of Fixer Upper from 2013 to 2018, the couple transformed homes and attracted a nationwide following.
While the duo already ran a successful home renovation business, including their retail store Magnolia Market, it was the exposure from Fixer Upper that truly helped turn their brand into an empire. Since then, they’ve expanded their influence with the Magnolia Network, a lifestyle product line at Target, publishing, and more, solidifying their place as power players in the home design industry.
Jesse James became a breakout figure in the early noughties as the no-nonsense star of Monster Garage, the Discovery Channel hit that turned custom car builds into must-watch TV.
The show didn't just showcase his welding skills; it also made his brand famous, turbocharging West Coast Choppers from a small-scale operation into a major name. Building on his reality TV success, James has expanded into clothing, publishing, and firearms manufacturing, proving that his biggest build wasn't a bike or a car but a multimillion-dollar business empire.
In 2010, an audition on The X Factor led to Louis Tomlinson being placed in One Direction, alongside Harry Styles, Niall Horan, Zayn Malik, and Liam Payne.
The boy band went on to sell many millions of records and embark on blockbuster global tours before announcing a hiatus in 2016. Tomlinson has since cultivated a flourishing solo career, adding to his already ample net worth. Away from the spotlight, though, he's endured profound personal loss, including the deaths of his mother and sister, and the tragic passing of Liam Payne in October 2024.
Niall Horan emerged from The X Factor as One Direction's boy-next-door, before successfully carving out a distinct path of his own once the band paused in 2016. Leaning into a softer folk-pop sound, he launched a solo career that's delivered chart-topping albums, including Flicker and Heartbreak Weather, alongside sold-out tours.
Away from music, Horan has boosted his earnings through TV work, brand partnerships, and a variety of business ventures.
Kendall Jenner grew up on camera on Keeping Up with the Kardashians, before charting a distinctive career path of her own. Leveraging the exposure into a full-scale fashion career, she's become one of the world's highest-paid supermodels, fronting campaigns for brands including Calvin Klein, Estée Lauder, and Fendi while walking the biggest runways in the business.
Add extra-generous appearance fees and eye-watering sums for sponsored social media posts, and Jenner has turned reality TV fame into a highly polished, money-spinning modelling empire.
Worth the same as her younger sister Kendall, Khloé Kardashian has taken a very different route to her $60 million (£45m) fortune. On top of extensive TV work, she's bagged brand ambassadorships, set up a fashion brand, and even launched a popcorn line.
Crucially, she now out-earns Kendall on social media. As one of the platform's top influencers, Khloé is reportedly able to command as much as $1.9 million (£1.4m) for a single sponsored Instagram post.
Texas-born Miranda Lambert first grabbed attention on TV talent show Nashville Star in 2003, finishing third but landing a record deal. Since then, she's become one of country music's defining voices, with several country number-one albums, smash singles like The House That Built Me and Mama’s Broken Heart, and a record haul of ACM Awards, plus side project Pistol Annies.
A savvy businesswoman, Lambert has also cashed in from money-spinning endorsements with major brands including Coca-Cola, Target, and Chevrolet.
RuPaul spent years building a cult following in music, fashion, and club culture, but his big breakthrough came in 2009 with RuPaul's Drag Race. What started as a niche reality show quickly went global, spawning multiple spin-offs and international editions.
The Emmy-winning franchise turned drag into mainstream entertainment and RuPaul into one of reality TV's highest earners, with millions of dollars flowing in from hosting, producing, and brand deals ever since.
The eldest Kardashian sister has done very well for herself since Keeping Up with the Kardashians launched in 2007. While her younger siblings chased fashion and beauty empires, Kourtney leaned into health and lifestyle, turning reality TV fame into her wellness platform Poosh and later supplement brand Lemme.
Together with hefty reality TV pay cheques, spin-offs, endorsement deals, and big bucks Instagram ads, Kourtney has the edge on Kendall and Khloé, but she still trails three other Kardashians financially.
Zayn Malik was the first member of One Direction to strike out alone, leaving the group in 2015 and quickly redefining himself as a solo artist. His debut single Pillowtalk went straight to number one on both sides of the Atlantic, followed by a chart-topping album, and a run of high-profile collaborations.
Factor in fashion partnerships and a lower-key but highly lucrative career path, and Malik has quietly pulled ahead of bandmates Louis Tomlinson and Niall Horan in the net-worth stakes.
Before becoming a Real Housewives of New York City fixture in 2008, Bethenny Frankel first tested the reality TV waters on The Apprentice: Martha Stewart in 2005, where she reached the final and learned the mechanics of turning exposure into leverage.
Using the Bravo show as a springboard, she launched lifestyle brand Skinnygirl, later selling the cocktail arm in a deal worth a reported $120 million (£89.6m). Frankel has made a mint from additional TV work, podcasts, self-help books, plus a whole lot more besides.
Already successful bar, club, and restaurant owners, Ken Todd and Lisa Vanderpump hit a new level after The Real Housewives of Beverly Hills launched in 2010.
The show turned the UK-born couple and their establishments into global talking points, paving the way for the hit spin-off Vanderpump Rules in 2013. They've also launched everything from a range of rosé wines to a pet accessories store, maximising the financial clout of their reality TV stardom.
Before the chart-toppers and Grammys, Cardi B's first real break came on Love & Hip Hop: New York, where the rapper's sharp wit and zero-filter personality made her a standout from 2015 to 2017. That exposure gave her a ready-made audience and the confidence to walk away and bet on music full-time.
The gamble paid off spectacularly. Bodak Yellow brought her global fame, and plum deals across music, fashion, and more have since pushed her net worth into nine figures.
Guy Fieri's road to riches began on The Next Food Network Star in 2006, a reality competition win that landed him his first show and $1,000 (£747) per episode. What followed was Diners, Drive-Ins and Dives, which made him one of food TV’s most recognisable faces.
Fast forward to 2025, and Fieri now earns a staggering $33 million (£24.6m) a year from the Food Network, which makes him the world's highest-paid TV chef.
Kyle Richards reinvented herself via The Real Housewives of Beverly Hills, joining the show at its 2010 launch and becoming its longest-serving original cast member. While she'd worked steadily as a child actor, reality TV put her back at the centre of pop culture and made her a star.
Between a reported $270,000 (£202k) per season, spin-offs, endorsements, and business ventures, RHOBH has been hugely lucrative for Richards, bolstering the fortune she built alongside her real estate mogul husband Mauricio Umansky.
Country megastar Carrie Underwood has turned her 2005 American Idol win into a blockbuster career and $120 million (£90m) fortune.
Multi-platinum albums, record-breaking singles, and humongous touring revenue form the core of her wealth, while endorsements, her CALIA clothing line, and a bestselling lifestyle book have pepped up her earnings even further. In fact, Underwood ranks as the richest female solo artist to come out of a reality TV music competition.
Harry Styles has out-earned every other artist to emerge from a reality TV music competition, becoming the richest solo star the format has produced. His post-One Direction career has been breathtakingly successful.
Styles has combined chart-topping records with a truly massive touring business. He's also cracked fashion and film in a way none of his bandmates have, with high-end brand deals with the likes of Gucci and headline-grabbing acting roles underlining his formidable star power and earning prowess.
The Kardashian empire exists thanks to Kris Jenner's shrewd business acumen and media nous. After Keeping Up with the Kardashians launched in 2007, she moved from cast member to chief operator, steering her family's rise to the A-list.
As the original 'momager', Jenner has taken a significant cut of her children's deals and locked in huge TV contracts and beauty windfalls, including lucrative stakes in KKW Beauty and Kylie Cosmetics. It's little wonder then that the matriarch of the clan is sitting on a fortune of $170 million (£127m).
The twin stars of Property Brothers have leveraged a breakout HGTV hit into one of reality TV's biggest fortunes. The renovation show has grown into a sprawling media and property empire, spanning multiple long-running spin-offs, a production company, and their Scott Living homeware brand.
Long before TV fame, the siblings were already buying and flipping houses, a head start that's helped turn on-screen popularity into a combined net worth of $200 million (£149m).
Paris Hilton didn't just star in The Simple Life with her pal Nicole Richie. She almost single-handedly defined the modern famous-for-being-famous reality TV celebrity. The noughties show turned her into a global name, but she swiftly proved she was so much more than a pampered hotel heiress playing up to a party-girl image.
Hilton has cashed in hard, building a vast licensing empire led by blockbuster fragrance lines that have generated billions in sales, alongside fashion, accessories, and endorsements.
A former New York family court judge, Judith Sheindlin became a pop-culture phenomenon in the 1990s with Judge Judy, trying real cases while winning over viewers with her straight-talking approach and razor-sharp wit.
The show dominated ratings for 25 seasons and made her the highest-paid TV star, with a salary that peaked at an extraordinary $47 million (£35.1m) a year. She's wisely boosted her colossal fortune with smart contract deals, including ownership of her episode library, along with a successful streaming revival Judy Justice.
Kylie Jenner has riffed off her reality TV fame to build a beauty juggernaut, tapping her enormous social following to turn Kylie Cosmetics into a global brand. A smash hit from its 2015 launch when lip kits sold out in minutes, she later sold 51% of the business to Coty in 2020 for $600 million (£448m).
Forbes named Jenner the world's youngest self-made billionaire in 2019, only to retract the claim amid allegations of inflated figures. Even so, the make-up mogul's fortune keeps climbing, with her net worth edging ever closer to billionaire territory.
The richest reality TV star of all time, Kim Kardashian gained widespread notoriety in 2007 following the release of a leaked adult tape, a moment that thrust her into the public consciousness.
That attention was quickly amplified by Keeping Up with the Kardashians, which transformed her from tabloid figure into global celebrity. She later channelled that fame into business, launching KKW Beauty (later SKKN by Kim) and, most lucratively, Skims. Founded in 2019, the shapewear brand is now valued at an eye-watering $5 billion (£3.7bn), cementing her status as a billionaire and the genre's ultimate success story.
