Taylor Swift, Katy Perry and Coldplay are taking a stand against global hunger by auctioning concert tickets and memorabilia for charity.
Swift is offering up an autographed guitar for the annual Hungerthon auction organised by the WhyHunger foundation, which raises money to provide food for impoverished families around the world.
Perry fans can bid on a pink satin jacket from the pop star's California Dreams Tour wardrobe, while Coldplay will fly their lucky winner to see them at a London gig in June (12).
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 (11).
