Usher became the latest artist to join James Corden for some “Carpool Karaoke” on Tuesday’s The Late Late Show. The duo sang Usher hits while also performing an unexpected good deed.

After entering the car, the two quickly found time to pull over in a parking lot so Usher could teach the late-night host some dance moves he could apply at the club.

Also, between singing and rapping along to some of the singer’s biggest hits, the two made unscheduled detours to Usher’s Hollywood Walk of Fame star, where they gave the plaque a good “spit-shine” cleaning and later pushed a broken-down Porsche down a Los Angeles street.

“I had no idea when I got in your car I’d end up pushing cars and cleaning my star” Usher noted before they launched back into “OMG.”
