Taylor Lautner is geared up for New Moon, and his expanded role in it–

But today, the actor most likely to be doing the dance of joy is the fast-rising, fan-kissing, underwear-signing Lautner. After establishing in the first film that he has a thing for Bella and the nerve to stare down Edward, he’s already busy practicing his lines for Jacob Black’s expanded role as a lover, fighter and werewolf in the next flicks.

“The quote I love the most is Jacob’s quote, ‘Does my half being naked bother you?’ That quote just cracks me up,” he laughed when we met him for the first time, on the “Twilight” set. “Because, you know, that’s when he’s shirtless, not wearing a top — we’ll have to wait to see what he looks like.”

Lautner is hoping to get a chance to prove his fighting skills:

Lautner plans to begin bulking up now that “New Moon” has received the official green light, and is also hoping to work some of his real-life martial-arts background into Jacob’s upcoming battles. “They found a YouTube video of me on ESPN when I was 11, and they were just freaking out and were watching it over and over again. … I said that it’d be cool if Jacob did some of that in the fight scenes,” he told us in August. “[Hardwicke] said, ‘Yeah, that would be cool.’ “

Here’s the fabulous video he’s speaking of–how cute!–
