Justin Bieber's redemption tour continued on Wednesday, with the singer addressing his emotional breakdown at Sunday's MTV Video Music Awards on The Tonight Show. Bieber told Jimmy Fallon that, while he was "disappointed" to have missed some cues during his set, the real reason that tears started to flow was because of the audience's loud applause.

[...] it appears to be working - his latest single, "What Do You Mean?" is currently No.
