Can you stand it, "Twilight" fans? There are only a few hours until the premiere of an exclusive clip from "The Twilight Saga: Breaking Dawn - Part 1," followed by a lengthy Q&A with stars Kristen Stewart, Robert Pattinson and Taylor Lautner as part of "MTV First: Breaking Dawn" tonight at 7:56 p.m. ET on MTV and MTV.com.

For those dying to know more about the clip Stewart, Pattinson and Lautner will be introducing, we have a special sneak peek for you right here, right now. The clip opens with Bella's mom entering the room in which Alice and Rosalie are helping Bella get ready for her wedding day.

"Crap, my mascara!" mom Renee Dwyer (Sarah Clarke) says when she sees Bella, at which point Alice hands her a tissue.

"Thanks," she says, dabbing at her eyes. "Charlie, get in here!" she calls to Bella's father (Billy Burke).

Charlie pops his head into the frame tentatively. "You sure?" he asks, at which point our teaser ends. Those in need of extra ogling and analysis can head over to Hollywood Crush for a photo from the clip, and then don't forget to tune in to MTV at 7:56 p.m. tonight to see the clip in its entirety, followed by a Q&A with the "Twilight" trio on MTV.com.

We haven't seen much from the highly anticipated nuptials between Bella and Edward, but Pattinson and co-star Peter Facinelli did tell us how pretty everything and everyone looked during filming.

"[Kristen] looked amazing," Pattinson told us of seeing Stewart in Bella's wedding dress. "I really didn't do anything much but just stand there."

"[The wedding scene was] beautiful and spectacular," Facinelli chimed in. "It's funny, because whenever we have a big important scene on 'Twilight' [movies], it rains. I was doing the baseball sequence [from 'Twilight'], and it was raining. But you never see it on film," he said of the crew's movie magic. "With this wedding, it rained the whole time we shot the two scenes. But you'll never see it on film; they block out the rain. They put tarps up, and you'll never see it. But for us, it was very wet and muddy and cold."

Be sure to tune in to "MTV First: Breaking Dawn - Part 1," which kicks off tonight at 7:56 p.m. ET on MTV, followed by a Q&A with Kristen, Rob and Taylor on MTV.com!
