Justin Bieber made the first live performance of 'Boyfriend' a big one as he killed the stage on 'The Voice' finale.  After his performance Bieber tweeted news of a new song for Mothers Day that would help raise money for single mothers everywhere.

Bieber took the stage just before Jermaine Paul was named the season two winner of 'The Voice'.

The camera made sure to focus in on Christina Aguilera during the performance considering the less than warm welcome she gave Biebs last time.
