The GRAMMY Charity Online Auctions has launched its Back To School Charity Auction and includes a selection of fantastic pop-based prizes.

Boyband One Direction have offered up an exclusive VIP concert experience at New York's famous Madison Square Garden, Adele has signed a 'Rolling in the Deep' CD, and fans can also bid to win a guitar signed by 'Teenage Dream' beauty Katy Perry.

Bidding for the One Direction prize will go live on July 21 and is set to close on August 1. There are other prizes up for grabs including signed memorabilia from the likes of Nicki Minaj, Usher, and Kelly Clarkson.

The 'What Makes You Beautiful' lads have been back in the studio working on new music and confirmed earlier this week that they've been writing songs with boyband McFly.
