Katy Perry is thrilled that someone paid $3,500 for a mold of her ample breasts.

Katy had a plaster cast of her D-cup bust auctioned for breast cancer research charity Keep-A-Breast in December-and the “Thinking Of You” singer was thrilled with the amount a fan paid for it.

“Someone paid $3,500 for a mold of my breast. That’s a lot in a recession,” Katy gushes.
