Playfully posing for photographers on hand, supermodel Petra Nemcova made her first appearance as the spokesperson for Otto, a German mail order company in Hamburg, on Monday (June 30).

And with the money that's rolling in from her numerous endorsement deals, the 29-year-old Czech cutie has been helping out those in need, as well.

Making the most of her trip to the Cannes Film Festival, Petra Nemcova has been dazzling onlookers in the south of France ever since her arrival.

Last night, the 28-year-old Czech supermodel sported a spring bud green dress as she schmoozed it up with fellow revelers at a benefit for the Prince Albert of Monaco Foundation.

While some celebrities get caught up in the hoopla of Hollywood, Petra Nemcova is using her star power to rally around some great causes.

The Czech supermodel 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.
