While they filmed their reunion show, the cast from Friends also took part in Carpool Karaoke with James Corden.
Jennifer Aniston, Courteney Cox, Lisa Kudrow, Matt Le Blanc, David Schwimmer and Mathew Perry were also driven around the Warner Bros studio lot by Corden who hosted that special reunion show which aired earlier last month.
The cast and Corden sang the Friends theme song "I'll Be There For You", while it was being blared on the speakers.
"I always wanted to do Carpool Karaoke", Courteney Cox said at the end of the song.
