The three actresses, who have remained close friends despite their show going off air 10 years ago, reprised their screen characters for a fan fiction created by host Jimmy Kimmel on his TV show, reported Us magazine.
Aniston, 45, read out her lines as Rachel with Kimmel, who enacted Ross Geller on the recreated set of the famous 'Friends' kitchen. Shortly afterwards, the duo was joined by Kudrow, 51, and Cox, 50, who played their parts of Phoebe and Monica Geller respectively.
The reunion is said to be linked to next month's 20th anniversary of 'Friends', which also starred Matt LeBlanc, Matthew Perry and David Schwimmer.
Another commemoration of the event is the New York opening of a replica Central Perk coffee shop, complete with Barista Gunther (James Michael Tyler) and photo opportunities for fans on the iconic couch of the infamous sitcom.
