Bob Harper revealed a secret on 'The Tonight Show' (Weeknights, 11:35PM ET on NBC), when he told a story he'd never told to anyone before. It involved him participating in a nude photo shoot for 'Playboy' magazine.
Years ago, in anticipation of her photo spread in 'Playboy,' Jenny McCarthy called up her favorite trainer and asked him to pose in the photos with her. According to Harper, she told him she needed a man in the photos and she wanted it to be him.
After some convincing, she got him to show up, but he refused to strip beyond his boxer shorts. Hilariously, when Leno showed the photos, all you could see of Harper was his arm in one shot, or his back and part of one leg in another. He's the ultimate extra!
