Jimmy Fallon Performs Justin Bieber’s ‘Baby’ — Sort Of

It was inevitable that the media would use Justin Bieber's massive hit "Baby" to mock him for the paternity suit filed against him last month. Mariah Yeater, 20, says that she took the Biebs' virginity after a concert at L.A.'s Staples Center on October 25, 2010, and that he left her with a little one, who's now three months old. But who knew that a "Baby" joke could be so funny? (Well, probably to everyone but the Biebs.)

Jimmy Fallon took to the stage of his NBC show "Late Night With Jimmy Fallon" Wednesday to perform a spoof of the tune called "(It's Not My) Baby." Just for kicks, Fallon even showed off some Bieber-esque dance moves in a very Justin-like ensemble.

Check out the clip:

On second thought, everyone has got to find that hilarious: Do you think Bieber is laughing?
