The Tonight Show's Jimmy Fallon revealed in a recent interview that Justin Bieber cancelled a planned sketch for his appearance on the show September 2 without any advance notice. The funnyman alerted fans of the show to the "Where Are You Now" crooner's big appearance with a tweet, saying "Doing something fun with Justin Bieber then he's performing with The Roots." In a twist of unfortunate fate, Fallon nor fans never got to find out what that "something fun" was going to be when Bieber cancelled only a few hours before he was set to start taping without a clear reason. Fallon said in the interview, "I mean, I wish they'd told me weeks ago because today's the day, and now we have to crunch and think of an idea to do. And I have to apologize to the crew guys who built the set and the wardrobe people and everyone."
