More details from MTV:

On Thursday, November 3, at 7:56 p.m. ET on MTV, we will premiere a never-before-seen clip from the hugely anticipated new film live on-air, to be introduced by megastars Kristen Stewart, Robert Pattinson and Taylor Lautner.

Immediately following the introduction and premiere of the clip, Stewart, Pattinson and Lautner will be sticking around for a lengthy Q&A session with MTV News’ Josh Horowitz — a chat that begins on air and continues on MTV.com. Who knows what will happen when the three stars actually get together in one room, because separately they’ve had some very intriguing things to say about one another. In recent conversations, RPattz has compared his sex scenes to “playing Twister,” while KStew has revealed that Taylor began one of their fight scenes by confessing to his co-star, “You’re so cute.”

Fans can get in on the anything-might-happen conversation immediately by submitting video or text questions beginning Thursday (October 27) via MTV.com or via Twitter (using @MTVNews, plus the hashtags #AskTwilight
and #MTVFirst).

Um….WHO’S EXCITED??!!?!?!?! Me me me me meeeeee!
