To round off a year of celebrations to mark the beloved beverage's launch in 1982, a host of British celebrities have set up their own 'Diet Coke Moment' for a series of stylish snaps.
The photos will be auctioned on eBay.com from 5 November (13), with all proceeds going to U.K. youth charity The Prince's Trust.
The images include Girls Aloud star Roberts taking a Diet Coke break in the studio, Frost relaxing with the fizzy soda in her London garden, and Friel taking meetings in the U.K. capital.
Peaches Geldof, model Daisy Lowe and designer Giles Deacon have also posed for shots.
Brid Drohan-Stewart, Marketing Director for Coca-Cola Great Britain, says, "2013 has been a phenomenal year for Diet Coke. As part of our 'Sparkling Together for 30 Years' campaign, we wanted to end the year of celebration with one big sparkling moment and give fashion fans the opportunity to bid for these exclusive pictures to raise money for a worthwhile cause."
