Justin Bieber Explains Why He Cried Onstage At The VMAs

On Jimmy Fallon's 'Tonight Show,' he also revealed when he's dropping his album.

Justin Bieber made his comeback performance on Sunday night at the 2015 MTV Video Music Awards -- but if you thought you were overwhelmed, think about how it felt for Biebs.

Our guy broke down into tears inexplicably after the gravity-defying performance, which had him flying up into the arena while singing his new song "What Do You Mean?"

On Wednesday night, Bieber was a guest on Jimmy Fallon's "The Tonight Show," where he explained why he got so emotional, blaming it on his desperation to be liked... and a few missed cues (although we didn't notice).

"I just wasn't expecting them to support me in the way that they did," Bieber said. "Last time I was at an award show, I was booed. I think I've worked so hard on this album. I've worked so hard at just becoming the man I want to become. Stepping into situations, you just can't help but feel judged. I was just feeling judged and wanting to win so badly and just wanting to do what I love so badly that I just put everything on the line.

"That's what's so special about the emotional moment at the end," he said. "It was authentic, it was real. I was really just wanting it so bad."

Bieber also told fans that his album will drop on Nov. 13, and did a country version of "Where Are U Now." And, hey, JB might have a future in country music!

Also, um, he's really good at drumming too. I mean, we knew that, but when he went up against Questlove, it proved his skillz even more.
