It was a very busy Monday for Taylor Lautner

Not only did the "New Moon" star have the world premiere of his movie to premiere, but he took some time out to help boost the ratings of NBC's struggling "The Jay Leno Show" (was Summit doing Leno a favor?).

Lautner discussed the advantages of hanging out with Senior Citizens in Vancouver during the off time of shooting "New Moon" and "Eclipse" but also brought yet another exclusive clip from the movie. 

The new preview shows Jacob (Lautner) trying to explain to Bella (Kristen Stewart) just why he has been so strange lately.  And, he's buff and shirtless as he is through most of the second half of the movie.

Check out the two clips below.
