Playboy babe Liz Dickson's knarly bruise from 'a$$ cheek golf tee swing' with Kevin Klein [PHOTO/VIDEO]: sexy model suing for injuries

The stunning brunette is currently suing Playboy for a whopping $500,000, claiming that the golf tee stunt resulted in some major injuries.

According to Dickson, Playboy reps had her lay on her stomach while Klien placed a tee between her butt cheeks and let it swing. The photo of her crazy black-and-blue bruise tells the rest of the story.
