KATY PERRY'S PROVOCATIVE PLASTER-CAST PULLS IN $3,000

Katy Perry's womanly charms have helped raise $3,000 for a cancer charity - a generous fan has snapped up a plaster cast of the singer's ample breasts.

The I Kissed A Girl star was covered in a plaster mould last year (08) while MTV cameras recorded the event for breast cancer research group Keep-A-Breast.org.And the curvy beauty had so much bust - organisers had to order extra plaster.She says, They had to get extra plaster to cast them because they are so big!But despite the added cost, Perry's plaster-cast has proved lucrative - the organisation has received a $3,000 donation from a fan in exchange for the mould.
