Music lovers packed The Colosseum at Caesars Palace on Sunday to see Usher in concert, but Kevin Hart stole the show.

Usher was performing his hit “There Goes My Baby” when the pint-size funnyman strolled onto the stage to get his sexy on. Hart posted a clip of the hilarious stunt on his Instagram page.

“Last night was EPIC…. Sorry @usher, but I had to do it…The music got a hold of me, and I felt like this was my moment to showcase my voice,” Hart captioned the video. “Shit got R rated up there real quick. I’ve been on the phone all morning turning down offers and recording deals…. I guess I bought real R & B music back….P.S My R & B walk is fucking KILLER….notice the foot kick with the heel to toe.”

The Ride Along comedian was clearly feeling himself as he gave the audience some vocals, all the body rolls and even a growl.

“It’s time for the X-rated part of the show,” he told the cheering crowd.

Thankfully, Usher was a good sport and let Hart have his moment.

The “Caught Up” singer is the latest music legend to start a residency at The Colosseum at Caesars Palace. He’s following in the footsteps of Elton John, Cher and Celine Dion. Usher started his tenure two weeks ago.

“To be greeted with the excitement of people who want to get out after being locked down the past year – and the fact that I’m playing a venue where legendary artists have played – it’s all just an honor,” the crooner told USA Today.

“Even as a kid, when I would look back and hear about Sinatra or Elvis, (Vegas) was always the place they went,” he continued. “This is the planned destination for anyone who considers themselves an artist who has made a contribution.”

Usher’s residency will end in January 2022.
