Gwyneth Paltrow definitely knows how to make a fashion statement. She attended the "Iron Man 3" premiere in Los Angeles on Wednesday wearing a provocative Antonio Berardi gown that proved she wasn't wearing any underwear.

The dress looked slightly disjointed from the front, but it was the side and back views that really got people talking. The gown featured sheer side panels that showed off her legs and butt cheeks.

The actress is already the talk of Tinseltown after being named People magazine's Most Beautiful Woman In The World. Paltrow, who plays Pepper Potts in the "Iron Man" franchise, has also been doing a press tour promoting her new cookbook, "It's All Good."

But not everyone is a fan of the A-list star. She recently landed the number-one spot on a "Most Hated Celebrity" poll released by Star magazine.
