Gwyneth Paltrow was just crowned People magazine's most beautiful, and she definitely made sure no one forgot that at the "Iron Man 3" premiere last night in L.A.

The actress wore an Antonio Berardi number that showed off her "most beautiful" figure by way of sheer panels down both sides. The dress left little to the imagination -- making it clear that this was an underwear-free night for the mom of two -- but she certainly lived up to her newly bestowed title.

Paltrow wasn't the only star at the El Capitan Theatre last night, of course. Leading man Robert Downey Jr., Don Cheadle, comic book legend Stan Lee, and Jon Favreau were also there for the festivities. At one point, the entire cast was showered with confetti, as RDJ blew kisses to the crowd. Oh, Tony Stark. So charismatic.

"Iron Man 3" pits brash billionaire Stark against a ruthless new enemy who destroys his personal world, and forces the superhero to embark on a harrowing quest to find out who is responsible.
