Stars back Sport Relief on Twitter
David Walliams, One Direction and Coldplay are among the stars taking to Twitter to raise money for Sport Relief in an online auction.
Little Britain star David is offering some of the swimming gear he wore during his Thames charity swim to the highest bidder, while Coldplay will be taking bids on a signed edition of their Mylo Xyloto album.
Other names taking part in Twitrelief include footballer turned Strictly Come Dancing star Robbie Savage, QI host Stephen Fry, presenter Gabby Logan and boy bands One Direction and JLS.
Gabby Logan said: "It's great that Twitrelief is back again this year.
"There are so many amazing prizes and experiences on offer and all the money raised by the public goes to helping change lives both here in the UK and the world's poorest countries. I'd like my prize to be the one that everyone bids for, so I'll be encouraging everyone out there to bid as much as they can and they'll be rewarded with lunch with myself and the lovely Clare Balding."
The auction ends on Sunday March 25.
