One guess what song they sang?
We just can't get enough Friends content, can we?
Many of you may already be familiar with James Corden's Carpool Karaoke.
It's a popular skit for the Late Late show hosted by Corden himself which sees him pick up celebs in his car to "get to work".
We then get treated to a singing showcase, as singers such as Billie Eilish and Miley Cyrus belt out their songs with Corden.
And now we have that, with a twist, as the host picked up the Friends stars to bring them to none other than the set of the famous Friends reunion.
He's flagged down by all six of the main cast, Jennifer Aniston, Courtney Cox, Lisa Kudrow, Matt LeBlanc, Matthew Perry and David Schwimmer.
Of course, we wouldn't call it karaoke if there was no singing right?
Naturally, Corden cranks up the music and plays The Rembrandts' 'I'll be There For You', with everyone joining in for the singalong.
Corden then takes the time to explore the Friends' set before sitting down for a chat with the cast.
They share even more secrets like who broke character the most and who stole the most wardrobe pieces.
