Justin Bieber sings to his 'Baby' on David Letterman Show
Justin was one busy little Bieber on Tuesday (March 23).
For those who didn't get their fill of Justin Bieber crooning to his "Baby" on "The View" Tuesday morning, he sang his hit again on "The Late Show With Letterman."
In Bieber's "Late Show" performance, he raps Ludacris' "Baby" verses, and he does some pretty smooth dance moves. And lots of hopping up and down.
All this in an effort to promote his album, "My World 2.0," which was released on the same day.
Up soon for the teen sensation: performing on "Saturday Night Live", April 10.
