A stand against global hunger has been taken by singers Taylor Swift, Katy Perry and Coldplay, who are auctioning concert tickets and memorabilia for charity.
Swift is offering an autographed guitar for the annual 'Hungerthon' auction organised by the 'Why Hunger' foundation, which raises money to provide food for impoverished families around the world.
While Perry fans can bid on a pink satin jacket from the pop star's California Dreams Tour wardrobe, Coldplay will fly their lucky winner to see them at a London gig in June.
'The Ramones' rocker Marky Ramone is donating drum lessons, while Green Day, Nickelback, Cyndi Lauper and Fleetwood Mac's Lindsey Buckingham have all signed electric guitars to go under the hammer.
The Charity Buzz online auctions will come to a close on 30 November.
