Justin Bieber Stops By Jimmy Fallon With New Single “(It’s Not My) Baby” When news broke on Wednesday that a 20-year-old woman had accused teen pop idol Justin Bieber of fathering her child (not bad for 30 seconds of work!), the world gasped collectively. Well, okay, maybe just the small segment of the population like entertainment blogs, celebrity gossip rags and your pre-teen sister. Still, that’s a sizable population of people! The Bieber was cagey enough — probably pushed by his PR team — to stop by the Late Night with Jimmy Fallon show to set the record straight. After watching his performance, you’ll have to agree that it seems like the case is closed on those pregnancy allegations. Anyone else moderately creeped out by Fallon’s Bieber impression? That’s damn good, though, especially the rap breakdown in the middle of the tune. Another well-played music parody by Fallon & Company. How did anyone ever doubt he would make a great late night host?
