Justin Bieber gets 'Baby' ready for VMAs with surprise concert

justin-bieber-varsity-jacket-chevy.jpgWhile 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."
