Robert Pattinson bit his lip and gave an adorable thumbs-up as he accepted the golden popcorn for best male performance at the MTV Movie Awards in Universal City this evening. He accepted the first honor of the night, which bodes well for all the categories Eclipse is nominated in. Robert bypassed posing for cameras on the way in, but Kristen Stewart rocked a tiny Balmain dress to hit the red carpet. The two are sitting side by side in the audience, and were spotted laughing together before Robert won. Friends With Benefits leading duo Justin Timberlake and Mila Kunis presented the award to Rob, and JT got a little handsy with his sexy costar. Robert and Kristen could have their own intimate moment on stage if they make it a three-peat in the best kiss category. In the past they've teased fans with almost lip-locks, though according to Robert they have nothing planned this time around. They'll also help present the first Breaking Dawn trailer, which made its debut online earlier today.
