The cast of Friends did an impromptu twist on James Corden's famous Carpool Karaoke sketch while filming their reunion show.

Jennifer Aniston, Courteney Cox, Lisa Kudrow, Matt LeBlanc, Matthew Perry and David Schwimmer were driven around the Warner Bros. lot by Corden, who hosted their big reunion show that aired last month.

During the tour of the filming location, Corden stuck the Friends theme song on the speakers and they all joined in.

At the end of the song, Cox said she "always wanted to do Carpool Karaoke."
