James Corden took fans behind-the-scenes of the Friends reunion.
In a hilarious Late Late Show segment, Corden drove the cast around the Warner Bros. lot, who hosted the reunion special last month.
While they were being driven around, the cast - Jennifer Aniston, Courteney Cox, Lisa Kudrow, Matt LeBlanc, Matthew Perry and David Schwimmer - took part in an impromptu Carpool Karaoke segment.
What song did they sing you ask? The Friends theme, of course!
Cox later admitted that she "always wanted to do Carpool Karaoke".
Corden then chatted to the cast about filming the emotional reunion special in Central Perk.
During a quick fire round of questions, the former co-stars revealed Lisa broke character the most on set, and shared who stole the most clothes from wardrobe.
