Not to burst anyone's bubble or anything, but if you want to live in the Playboy Mansion, you gotta look hot. Gain a few and you'll face the wrath of the Hef. That's what his ex-girlfriend Kendra Wilkinson told US Weekly, anyway, in an interview with fellow ex-girlfriend Bridget Marquardt. "[I said] 'I'm getting kind of fat' and Hef Said 'yeah, there is a gym downstairs' ... I was crying so bad!"

Still, you won't see either Kendra or Bridget signing up for Jenny Craig anytime soon. "The word 'diet' is stupid and I don't believe it!" Wilkinson says, and 110-pound Marquardt adds, "It's a bad word." But they do believe in fitness. Kendra sweats it out at the gym, while Bridget loves Trapeze. "[I love it when] I've performed a trapeze routine and done a really great job. And even though I'm sweaty and nasty and gross from it, I just feel so accomplished and good."
