Justin Bieber tapped into his sensitive side for his first round performance on Lip Sync Battle.

The singer tackled Fergie's 2006 hit "Big Girls Don't Cry" in his battle against Deion Sanders, finishing off the song with an epic taunt to the former football player. Quite the contrast to his performance in the second round of the face-off, where he breaks out a wig and eyeliner for Ozzy Osbourne's "Crazy Train."

19 times Chrissy Teigen's face was the true star of Lip Sync Battle

Take a look at his ballad and check out a clip of his Ozzy-persona in the show's trailer.

Bieber's episode airs this Thursday at 10/9c on Spike.
