VIDEO : Justin Bieber is Ruining His 'big' Comeback One Talk Show at a Time

Justin Bieber pulled out of a planned Tonight Show skit at the last minute.
The What Do You Mean? singer appeared on Jimmy Fallon's show earlier this month and although it appeared to go off without a hitch, Jimmy admitted that Justin opted out of a sketch they had spent weeks preparing at the last minute.
Speaking to Billboard, he said: "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 say sorry to the crew guys who built the set and the wardrobe people and everyone."
The cancellation was even more disappointing for Jimmy as just hours before the show he tweeted that Justin would "do something fun" before his performance.
