Say what you will about the Biebs, but the bad boy pop star proved he's still got his vocal chops when he popped into the W Hotel in Hollywood for a surprise performance on Sunday at the venue's Jazz Night. 

Justin Bieber sang the 90s classic "I'll Make Love to You" by Boyz II Men and belted the sultry tune in front of an enthusiastic crowd. 

Bieber has had a troubled past few years fighting Photoshop allegations, dealing with his tumultuous relationship with ex-girlfriend Selena Gomez and running into trouble with the law. Even Bruce Jenner has issues with the young crooner. 

But Bieber has let his fans know that he has feelings, too, and he knows he's not perfect. He may not be proud of some of his past behavior, but when it comes to raw vocal talent, he's got nothing to be ashamed of.
