Last week, Justin Bieber threw us some car tunes with James Corden, including a modern twist on the classic Boyz II Men 1991 track "End of the Road." Bieber is known more for his cheesy pop than his swoon-worthy serenades. Still, he impressed the ladies with an impromptu performance at Jazz Night at the W Hotel in Hollywood on Sunday. If anything proves the Biebs is growing up ? or at least trying to ? it's his move into impressing those who feel nostalgic about these tunes. Sure, he'll always be an arrogant dweeb to most but he sure knows how to turn on the smooth.??
