Markus Molinari videotaped his friend Katy Perry as the singer had a plaster form applied to her torso for Keep A Breast, a non-profit breast cancer awareness organization which creates the plaster forms which are then customized by artists and auctioned to raise funding for breast cancer. Perry’s torso will be painted by her boyfriend Travis McCoy of Gym Class Heroes. “Just can’t mess with the 32D’s,” Perry said while pointing to a smaller plaster form. Watch the clip via MTV below.
