Watch Bruno Mars' awesome cover of Justin Bieber's "Baby"!


Hey M Girls,

Justin Bieber's "Baby" is a huge favorite of ours over here at M -- and we're not alone! Recently, when Bruno Mars stopped by a Texas radio station to perform for some lucky listeners, he asked the audience for requests. Instead, a little girl shouted out, "I know your Justin Bieber!" LOL! After that, Bruno decided to sing Justin's smash single "Baby". Check out the awesome cover below!

So let's dish: -Did you think Bruno sang the song better then Justin Bieber himself? What do you think Justin's reaction would be if he saw this?
