VMA will be mine !!

While most parents have to bribe and threaten to get their kids to rehearse anything on a regular basis, 16-year-old Justin Bieber took to an outdoor stage at the Staples Center in Los Angeles for two hours on Friday (Sept. 10). He was practicing for his performance at Sunday's Video Music Awards, but as an added bonus bystanders got a free concert.

Well, a free concert comprising of one song -- "Baby" -- over and over again.

According to the AP, the pop star took his rehearsal seriously, pointing out that "the vocals are too loud in my ear and I can't hear the groove.

"VMA viewers can expect Justin to be brought out in a red 1957 Chevy Bel Air, wear a red varsity jacket, be chased by a bunch of girls and be backed by a bunch of tween hip-hop dancers.

You know, the usual.During the rehearsal, he was also concerned that the drum solo wasn't loud enough. "This has to be, like, an epic moment," he insists. "It's ending the song."
