As "Twilight" fans know by now, today is a big day as we count down the hours until "MTV First: The Twilight Saga: Breaking Dawn - Part 2." This exciting event will feature an exclusive sit-down with Kristen Stewart, Robert Pattinson and Taylor Lautner, during which they will introduce a never-before-seen clip from the film on MTV.

You can see a teaser of this never-before-seen clip via the photo above. Just look at how excited Bella and Edward are for you to see them ... do whatever it is they're about to do in this new footage. (Can't ruin the surprise!)

Following the on-air introduction of the exclusive clip tonight at 8 p.m. ET, the "Twilight" trio will stick around for a lengthy interview on MTV.com, during which we'll cover the most pertinent and highly anticipated aspects of the fifth and final film in the franchise, as well as the stars' favorite memories from all five films. Fans can get in on the action immediately by submitting video or text questions via MTV.com or Twitter (@MTVNews, hashtag #AskTwilight).

The emotional impact and anticipation surrounding the end of this epic franchise is a heady subject. It's the end of an era! We were also lucky to broach the topic with the woman who started it all, Stephenie Meyer, who reflected on seeing the finished film for the first time.

"There's no way not to [be emotional] with the end of this one. [Director] Bill [Condon] has a very good sense of how to really wring your emotions," she said. "He put the end together in such a way that I don't think you cannot have a moment. I can only imagine the fans will really appreciate that moment of reflection."

How's that for expert teasery? We can't wait to hear what Stewart, Pattinson and Lautner have to say on the subject. Be sure to tune in to MTV at 8 p.m. ET sharp to hear it all.
