Justin Bieber Sings "Baby," "Never Say Never," and "OMG" at the Grammys in 2011
We love the trio of songs Justin Bieber performed at the 2011 Grammys. It was a special moment not only because he was nominated for two awards but also because Usher joined him on stage. The collaboration showed just how far the kid had come not long after Usher endorsed him as the next big thing.
