I absolutely love Justin Bieber, so I was super bummed to learn of the recent allegations that the Biebs has fathered a child. But it’s also great news for comics, who have found Bieber to be particularly ripe for parody. So I can’t say I was surprised to see Jimmy Fallon donning Bieber-style duds and busting out a song that lampoons both the kid’s music and the paternity accusation. Fallon performed “(It’s Not My) Baby” last night, and actually did a pretty solid impression. Plus he looks adorable in that hat – even if he isn’t as adorable as Biebs.
