The prospect of an exclusive clip from "Breaking Dawn" already has Twilighters buzzing about Sunday's MTV Movie Awards, but the exclusives don't stop there: MTV is planning another special first look, which will roll out during the red-carpet pre-show.

We know what it is and the "Breaking Dawn" stars know what it is, but viewers will have to wait until sometime Sunday between 7:30 and 9 p.m. ET/PT on MTV for the reveal. And just to tease you a bit more, Elizabeth Reaser (a.k.a. Esme Cullen) put together a list of three clues to set you off in the right direction.

"Is it possible that there was a butterfly involved? Did I give it away? Or I might have just hallucinated that," she said from the Sneak Peek Week red carpet for "The Art of Getting By." "I would assume that there would be some lavender involved -- lavender and or purple -- however you want to describe that. And it is the most coveted invite in town."

Jackson Rathbone also wants fans to watch the show, and he promises the surprise will be worth it. "If you tune in to the MTV Movie Awards this Sunday, you're going to see something ultra-special at the red carpet," he said. "That's right, something you've been waiting years for, and we're really excited to show it to you, so make sure you tune in."
