"I think her body is insane," the former Las Vegas star, 36, told Usmagazine.com at a Burberry event in NYC Thursday. Biel, however, might not take it as a compliment. She recently told Allure magazine that her good looks are hurting her acting career.

Can you believe these stars dated?

"Yeah, it really is a problem," the star, 27, said. "I have to be blunt." Plus, the actress -- whose latest film, Powder Blue, (in which she plays a stripper) is going to straight to DVD -- only has eyes for her current beau.

"I mean, you love who you love!" Biel said. "It's not like you meet somebody one day and say, 'Okay, I'm not going to put up with his fame!' or 'Yes, I am going to put up with his celebrity,'" she says. "You can’t choose that. It just happens to you."
