If you watched as Justin Bieber let the tears fall at the MTV Video Music Awards on August 30, the singer has now explained that you were witnessing a man in total conflict.

Bieber, who performed high-stakes renditions of new songs "Where Are U Now" and "What do You Mean?" at the show, told Jimmy Fallon on yesterday's (September 2) Tonight Show episode that a combination of disappointment in his execution and a renewed love of his craft ultimately reduced him to sobs.

"It was just so overwhelming for me, everything," he says in the clip above. "I missed some cues, so I was a little disappointed."

Still, he felt a connection to the audience, he notes, which was especially apparent since his previous routines hadn't gone over so well.

"I just wasn't expecting them to support me in the way they did," he shares. "Last time I was at an awards show, I was booed."

"I've worked so hard at becoming the man I want to become, and then stepping into situations, you just can't help but feel judged," he added. "So I was just feeling judged, and wanting to win so badly, and just wanting to do what I love so badly...That was what was so special about the emotional moment at the end: It was authentic, it was real. I was really just wanting it so bad."

Check out the interview, and hang tight for Bieber's new album, which he revealed is going on sale in November.
