Gwyneth Paltrow Admits To Her Least Favorite Physical Feature On 'The Tonight Show' (VIDEO)

"The Tonight Show" had the honor of hosting the World's Most Beautiful Woman, according to People magazine. Gwyneth Paltrow was pretty surprised about the honor.

"I’m 40. I have two kids, and that’s pretty effing awesome," she said candidly.

Perhaps less awesome is the fact that she was also ranked as the Most Hated celebrity in a poll by Star magazine. Actually, those two might go together better than would at first appear.

But Paltrow isn't a fan of all of her physical features, as she admitted to Jay Leno. "It’s to do with buttcheeks," she said. But as Leno pointed out, she didn't seem to worried about it in the dress she wore to the premiere of "Iron Man 3." That number was sheer all the way down both sides.

"There was no underwear on in that dress," Paltrow admitted. "I put it on and it stayed in place, thank goodness.”

Gwyneth Paltrow can be seen in "Iron Man 3," opening May 3. Catch "The Tonight Show with Jay Leno" every weeknight at 11:35 p.m. ET on NBC.
