Jimmy Fallon Spoofs Justin Bieber: '(It's Not My) Baby' (VIDEO)

After being slapped with a paternity lawsuit earlier this week from an alleged one-night stand, 17-year-old heartthrob Justin Bieber's squeaky bubblegum image is being called into question.

Bieber's camp is of course vehemently denying the allegations, but when your fan base is a bunch of frenzied tweens, it's important to get your message out there in an approachable way.

Since Jimmy Fallon is no stranger to Bieber spoofs or singing, and because Bieber's most popular single to date is the aptly named "Baby," it seems only appropriate that Fallon decided to take a stab at some PR on Wednesday night's "Late Night" and serenade his audience with reworked lyrics.

Clad in a leather jacket and that signature swoop haircut, he presented "(It's Not My) Baby" with accompaniment by The Roots, and we're not music journalists, but we smell another hit.
