What a high-class problem Bella Swan has. Choose her best friend, hunky Jacob Black, or her true love, broody Edward Cullen. Those who've read the 'Twilight' books by Stephenie Meyer already know the answer to that question. The rest of us will have to wait until 'The Twilight Saga: Eclipse' arrives in theaters June 30.

We'll get plenty of sneak peeks until then, and one of them aired on 'Entertainment Tonight' (weekdays, syndicated). Kristen Stewart, Robert Pattinson and Bryce Dallas Howard, who plays the deadly vampire Victoria, explain a little about their characters.

The entire time I watched this clip from last night's Late Night, I was thinking, "if Taylor Lautner smashes into a wall face-first or falls off of the mini-bike and cracks his head open, Fallon is going to be in big trouble." The two guys raced around the NBC hallways on mini-bikes. The winner wins because he cheats.
