London, Nov : Katy Perry has put a plaster cast of her boobs up for auction.

The 24-year-old singer, who has dismissed reports that she has enhanced boobs, is donating the plaster cast of her ample 32DD chest to raise money for the Keep a Breast Foundation.

Bids on eBay have reached 300 pounds, reports the Mirror.

While snubbing rumours claiming she had gone under the knife for breast enlargement, Perry said that she would never splash money on fake boobs.

Perry said that though she did not hold anything against those who did go for a cosmetic surgery yet she could not see herself as one of them. (ANI)
