Katy Perry has donated a sculpture of her bust to raise money for a breast cancer charity. The "I Kissed A Girl" hitmaker's chest mold will be painted by her boyfriend - Gym Class Heroes frontman Travis McCoy - and auctioned off in aid of the Keep A Breast Foundation's youth outreach program, according to E! Entertainment.

Bidding for the sculpture will open on November 26.

Other acts who have contributed to or painted busts for the sale - on auction website eBay - include Iggy Pop, Sonic Youth's Kim Gordon, and new wave rockers Devo.
