Another celebrity who has been auctioning off possessions to raise money for charity is Jennifer Aniston. The Friends star put a black and white nude portrait of herself up for sale in June, and it was expected to sell for up to $7,000 (£5.2k). In fact, the iconic 1995 shot made more than twice its estimate, and the hammer came down at $16,250 (£12.1k). All the money raised went towards NAF Clinics, which provides women’s health services.
