Parties: The Stars Shine at the MTV Movie Awards [Photo Gallery]

The MTV Movie Awards brought out Hollywood's most beautiful (and seriously weird) stars on Sunday, May 31. Everyone vied for the coveted Popcorn Award, and had a great time, except Eminem and his entourage, who swept out of the Universal Studios Ampitheater when Bruno (AKA Sacha Baron Cohen) fell from the rafters and stuck his bare butt in the rapper's face. By the way, we hear that was all an act, staged by those two strange bedfellows.

That was not pretty, but mostly these photos shot by Christina Radish are, especially the one of "Twilight" and "The Twilight Saga: New Moon" stars Taylor Lautner, Kristen Stewart, and Robert Pattinson (shown at left); they made audiences worldwide swoon.
