Katy Perry is doing more than just kissing girls these days. Her latest venture is creating a mold of her own breasts, which will then be auctioned off. The proceeds are going to breast cancer research through Keep-A-Breast.org later this year.

In other Katy news, MTV producers are reportedly working really hard at trying to score Lindsay Lohan for an on-stage smooch with Katy for this year's VMAs. Wishful thinking, though, because just last month, Lindsay refused to be photographed with Katy at the Hard Rock in Chicago. Who do you think should be MTV's second choice?
