Usher is the latest musical sensation to join James Corden on his commute to work.
The duo didn't spend all their time belting out tunes though. They took the opportunity to visit Usher's star on the Hollywood Walk of Fame and after noticing it was a little grimy, they applied a little elbow grease to spruce it up a little bit.
They also did some good deeds along the way, pulling over to help push a stranded car off the road. They're a lovely pair of lads really.
