The Czech supermodel Petra Nemcova was spotted at the Diamonds Empowerment Fund’s celebrity photo shoot for their Diamonds Give auction yesterday, looking sexy in a purple ruffled shirt, purple hat and a pair of vintage jeans.

And when she’s not helping out the Diamonds Empowerment fund, Petra is focusing her efforts on doing what she can for the Somaly Mam Foundation in an effort to raise awareness about the sex slave trade and human trafficking in Asia.
