Katy Perry fans can bid in an auction to handle her breasts.

The outrageous I Kissed a Girl singer, 24, who has blasted claims she has enhanced boobs, donated a plaster cast of her ample 32DD chest to raise money for the Keep a Breast Foundation.

The resulting… er, bust was painted by her boyfriend Travis McCoy from Gym Class Heroes.

Bids on eBay have reached £300.

Hoping to be remembered for your voice, Katy?
