Justin Bieber surprised a bunch of people when he showed up at the W Hotel in Hollywood, Calif., Sunday night (May 24) for an impromptu performance of the '90s R&B slow-jam "I'll Make Love to You" by Boys II Men.

The W Hotel was reportedly hosting its usual jazz night and was attended, we assume, by guests interested in hearing some jazz tunes. Leave it to Justin Bieber to be aware of the fact that nothing pairs better with an evening dedicated to jazz than a surprise performance of a '90s R&B hit by a modern-day superstar like himself. It may be pretty far removed from the evening's premise to commoners like you and me, but that's okay because Justin Bieber is the glue that binds us all together, and he knows that. Now the rest of the world knows it, too.

It's a little hard to hear his vocals, but from what we can tell it sounds like Justin did a decent job on the track. At one point he even attempts to do the worm right there on the stage floor, or maybe he's just thrusting against the floorboards for some undisclosed reason. In any case, it looks like it was a lot of effort on his part, and it was over before it really got started.
