Jessica Alba Shows Off Her Dance Moves on 'Late Night' (VIDEO)

"Do you go to clubs?" Jimmy Fallon said to Jessica Alba. Wait. Is this an interview, or is this a pick-up line? On 'Late Night' (weeknights, 12:37AM ET on NBC), Jimmy and his guest discussed the various aspects of "clubbing" -- while simultaneously saying that they were way too old and wrinkled to go out to night clubs.

But wait! Jessica Alba is only 29. And she's been named the sexiest woman in the world by 'FHM' magazine. (Sadly, 'Maxim' magazine only ranked her as the second sexist woman alive.) If she isn't cool enough to go clubbing, what hope is there for us mere mortals? Still, Jessica and Jimmy were self-deprecating while discussing the whole "club scene," referencing their own highly awkward "head-bobbing" dance style.

But Jessica did admit that back in her younger days (maybe back at the ancient age of, say, 28), she used to "clear the floor" and "go all out" at the dance club. She then stood up and proceeded to demonstrate. ... Yay! But next, Jimmy got up and displayed his own more sad-trombone-ish dance moves. Which got a slightly less "yay" reaction from the audience.
