On Tuesday's Tonight Show, Jimmy Fallon asked Justin Bieber why he cried at the end of his performance at Sunday's MTV Video Music Awards. "It was just so overwhelming for me, everything," Bieber said: "The performance; I missed some cues, so I was disappointed at that; and just everyone.... I wasn't expecting them to support me in the way that they did." The last time he was at an awards show, the crowed booed him, he added.
