Pop star Justin Timberlake, pocketed $6 million for delivering the I’m Lovin’ It jingle for McDonald's in 2003. In 2022 dollars? That's a cool $9.8 million (£8.1m).
JT was far from proud of the partnership though, admitting in 2007 to the British edition of GQ magazine that "I regret the McDonald’s deal", although he didn’t elaborate as to why he wasn't Lovin' It.
