If you’ve been following the last in pop culture news, then you should be aware that a 20-year-old California woman filed a paternity suit against teen idol Justin Bieber. Biebs is denying it of course, but that doesn’t mean late night host and Bieber impersonator Jimmy Fallon can’t play around with the hit single “Baby” and intelligently turn it into “(It’s Not My) Baby” noooo! Jimmy hits all the right notes and Roots rapper Black Thought plays a convincing Ludacris feature in the spoof embedded above.

And as the post title alludes to, Jimmy teamed up with Justin Timberlake yet again for “History of Rap 3.” That one’s waiting after the break.
