Jimmy Fallon recently revealed that Justin Bieber cancelled his planned sketch for his appearance on 'The Tonight Show' at the last moment.
In a recent interview, the 40-year-old TV host said he had to apologise to the crew and everyone else, and added that the 'Baby' hit-maker should have told him about this weeks ago, E! Online reports.
The comedian added "Today's the day, and now, we have to crunch and think of an idea to do."
Bieber had called off his appearance for the September 2 show without giving any advance notice.
