Whenever R. Kelly touches down in a city, he loves interacting with the people. During his recent trip to Jacksonville, Fla., the R&B vet ran into a drunk guy who tried to out sing him. And it was all caught on video.

In a clip shot by DJ Dr. Doom, a white man, who appears to be very intoxicated, accused the Chicago singer of being an imposter. He then bets DJ Dr. Doom a $100 that R. Kelly can’t carry a note and challenges him to a sing-off.

Kelly then obliges the drunken man with a rousing a cappella rendition of the intro to “Bump and Grind.” Despite delivering a perfect vocal performance, the drunken man wasn’t convinced it was the real R. Kelly.

In fact, the intoxicated guy tried to out sing him when his sorry “White Boy” rendition of "Bump and Grind," which he failed miserably.

Unfortunately for DJ Dr. Doom, the white guy didn't have a $100 but he did have $15 to spare.

In the end, it was all fun and games. No harm, no foul.

But let this be a lesson to anyone who likes to get inebriated. If someone approaches you and can perfectly sing "Bump and Grind" a cappella, it might be R. Kelly.

Watch the hilarious video above.
