Aww! He's so sensitive!

Justin Bieber sat down with Jimmy Fallon last night and of course the host had to ask what was on everyone's mind -- his MTV VMA breakdown on Sunday night.

The Biebs explained the emotional outpouring, "It was just so overwhelming for me," the "Baby" singer explained. "Everything, the performance, I missed some cues so I was a little disappointed with that," he added.

The 21-year-old added, "And everyone — the support — I was honestly wasn't expecting them to support me in the way they did. Last time I was at an awards show I was booed. I've worked so hard at this album, I've worked so hard at becoming the man I want to become. Then, standing in the situation, you just can't help but feel judged, so I was just feeling judged and wanting to win so badly, and wanting to do what I love so badly, that I just put everything on the line."

Aww! Biebs just wants some love!

We polled our readers about why they thought the Canuck was crying and 62 percent of you guys thought that the sob story was a clever ploy set up by MTV, but only 25 percent thought it was because he got emotional performing for his fans. Only 11 percent thought that Bieber broke down because of Selena Gomez -- but given the hidden shout out in his new video, it's entirely possible he was crying because of the cutie pie -- and he's trying to save face now!

In addition to the breakdown, the Biebs seems to be leaving secret messages for his former flame, Selena Gomez, in his "What Do You Mean?" music video. Fans spotted the name "Selena" was spray-painted in pink on a wall of graffiti in the sexed-up music video. We aren't sure what message it sends to his ex when he's feeling up another lady? But JB always does his own thang when it comes to Selena!
