Justin Bieber makes surprise appearance at W Hollywood, performs Boyz II Men classic

Bieber just keeps popping up!

Justin Bieber made a surprise guest appearance in Los Angeles at the W Hollywood's weekly jazz night on Sunday and performed a steamy cover of Boyz II Men's "I'll Make Love To You."

The pop sensation's risqué rendition of the '90s classic had the audience going wild. Even though the 21-year-old wasn't actually alive at the time the R&B song was released, he sure put a ton of life and emotion into his performance. At one point, he even got down on the floor to do the worm. After all, his dance moves have never failed to impress us.

But this isn't the first time the Biebs has done a surprise performance before. In fact, the "Believe" singer is known for surprising fans at different locales around the globe for impromptu concerts.
