Paper mache is a medium almost all of us have worked with in school at one point, and now artists and musicians are putting this skill to some good use.  A mold of Katy's torso is being made, then painted by Travie McCoy (of Gym Class Heroes) and auctioned off to a lucky winner during this breast cancer charity stunt.

You can buy her cast by visiting *** Keep A Breast ***.  It will be auctioned off in a gallery style.

Katy's breast cast sold for $3000 in 2009 when the auction took place!
