Justin Bieber Fans Cry, Collide During L.A. Tour Stop

'We're all running into each other, bumping each other in the head on accident,' one fan tells MTV News at the Nokia Theatre.

A gaggle of Justin Bieber fans descended on the Nokia Theatre in Los Angeles on Tuesday night to see their pop idol in concert. It was the latest stop on the Biebs' My World Tour, which kicked off earlier this summer in Hartford, Connecticut. And judging by the response after the show, Bieber definitely delivered.

One L.A. fan described the concert experience as "the best day of my life," and that seemed to be the general consensus from the crowd.

"It was amazing," a tween fan raved to MTV News once the show ended. "I've been to, like, every Justin Bieber show in Los Angeles and this was probably my favorite."

Yet another fan revealed that the vibe inside the Nokia was so intense that fans kept bumping into one another.

"We were so excited we could barely stand next to each other," she said. "We're all bumping into each other. We're all running into each other, bumping each other in the head on accident. It's everything [that makes me love him]. You know he has that perfect hair. He has that little hair swoop."

A teen Bieber fan had a confession: "I thought I would never cry. I cried on this concert." It seems Justin's performing the ballad "Down to Earth" inspired serious tears. In fact, the song has become something of a fan favorite on the My World Tour, with one admirer saying she loved "when he got up and he was floating on the heart. It was really hot."

By the end of the concert, though, it was clear that many fans couldn't pin down exactly what it was about Bieber that had made them swoon most.

"His smile. His hair — the way he flips it. His eyes. The way he sings, the way he dances," one fan gushed. "He's captivating. He's a performer. He's all of the world."
