In an effort to help the Keep A Breast Foundation, Katy Perry is having a mold of her torso created to be auctioned off for money ... and wait until you hear who will be designing the mold.

"It's like paper mache, when you're in first grade and you make a paper mache ball, but now they're using my boobies ... And [boyfriend] Travis [McCoy] is going to paint it." Perry told MTV News. "I think this is going to be auctioned off, and I think the auction will go for a week ... and I'm gonna blog about it, and spread it."

It's good to see that Perry can find humor in the very long process of being molded. After catching a glimpse of a previous 'smaller sized' mold, she exclaimed, "You just can't mess with the 32D's!"



Perry ends the video blog with some very important parting words ... "Eduate yourself and also do something for someone else by making this the highest bidded breast mold ever."

Perry just finished an entire summer performing on Warped Tour and has begun shooting a music video for her next single "Hot N Cold." Her breakout single, "I Kissed a Girl", spent seven weeks at number one on the Billboard Hot 100 and she has been nominated for Best New Artist at the 2008 MTV Music Awards (airing on September 7 at 9p.m. ET).

How much would you bid on Perry's mold? Do you think it's wrong for young kids to be exposed to videos like this one, or it acceptable because of the cause?
