Sexy supermodel Joanna Krupa showed off what makes her so famous in a sexy black bikini for Beach Bunny swimwear.

Modeling a zippered bikini -- which could make for some interesting tan lines -- Joanna joined the Kardashians (who also design swimwear for the company) in promoting the sexy swimwear.

But Joanna's not just a pretty face -- over the weekend we saw the Polish-born beauty making a charitable trip to her native land to deliver gifts and food to children at a local orphanage (gallery below.)

Beauty AND heart!
