Gwyneth Paltrow Forgets Underwear At 'Iron Man 3' Hollywood Premiere (VIDEO, PHOTOS)

Business at the front, party at the back!

Gwyneth Paltrow ditched her underwear in a risqué Antonio Berardi gown at the "Iron Man 3" premiere in Hollywood on Wednesday night.

The "Most Hated" AND the "Most Beautiful" actress showed off her gorgeous gams and a hint of sidebum in a long, flowing dress with sheer side panels and kimono-inspired sleeves. Looks like someone has been doing their pilates with trainer-to-the-stars Tracy Anderson!

Gwyneth, who plays Tony Stark's girlfriend/employee Pepper Potts in the "Iron Man" series, kept her blond locks blow dried straight and swept to the side in a simple cut, so as not to distract us from her eye-popping outfit.

The 40-year-old mom-of-three has been on a whirlwind "Iron Man 3" press tour these past couple of weeks and has blown us away with her fashion-forward outfits (see her sexy tuxedo dress and a structured floral look she recently wore), not to mention a dazzling satin gown she wore to a Tiffany's event she attended on April 19.

What we really want to know is: Was Gwyneth comfortable not wearing underwear? Was she afraid of a possible wardrobe malfunction? How does that work, exactly?

We're not style-savvy enough to come up with answers, so Gwyneth, we tip our hats to you!
