The singer of the hit song I Kissed A Girl had a plaster cast of her breast made for breast cancer research charity Keep A Breast and someone bought it for $3500.

She said: “Someone paid $3500 for a plaster mould of my breast. That’s a lot in a recession.”

Katy, 24 said she had no plans of ending her beef with Lily Allen, who previously claimed Katy called her “fat”. “When someone wants to go at it with me I’ll come back with all guns blazing!”

Back to the plaster cast, I hope it was a girl that bought it because I would hate to think of what a guy would do with it… Like add more plaster to it.. GROSS.
