Chris Brown wasn't the only pop star on live television tonight. Justin Bieber also made an on-stage network appearance, performing his new single "Boyfriend" for the very first time on the season finale of The Voice. Biebs was a triple threat- rhyming, singing, and putting his gold high-tops to work with some fresh dance moves. Believe hits stores June 19th. Swaggy.
