Justin Bieber looks like he's in agony lip synching 'Big Girls Don't Cry'

Justin Bieber Gives Swoon-Worthy Lip Sync of 'Big Girls Don't Cry'

It's going to take some fierce competition to beat Justin Bieber in lip synching.

The 21-year-old will perform Fergie's "Girls Don't Cry" for Spike TV's Lip Sync Battle, but he might just make you cry in the process!

Turning up the emotion, the "Baby" singer channels Fergie's lyrics, "And I'm gonna miss you like a child misses their blanket. But I've got to move on with my life."

Is that a dagger he's putting into his heart or ours?

The emotional side of Bieber is one that differs from his recent silly-side of posting a risqué photo of his naked butt.

On Monday, he regretted that decision and not only removed it but wrote an apology.

"Hey, I Deleted the photo of my butt on Instagram not because I thought it was bad but someone close to me's daughter follows me and she was embarrassed that she saw my butt," he captioned a pic of himself fully clothed. "And I totally wasn't thinking in that aspect. And I felt awful that she felt bad. To anyone I may have offended I'm so sorry."

But the real apology may need to happen on Thursday for former NFL player Deion Sanders as he squares off against the Biebs on Spike TV's Lip Sync Battle at 10 pm.
