The actors, who played Chandler Bing and Phoebe Buffay on the hit US TV sitcom Friends, will reunite on the upcoming fourth season of Kudrow’s programme about therapist Fiona Wallice, who doles out advice to patients online.

Perry is the fourth Friends star to make a cameo appearance on the show.

Matt LeBlanc, Courteney Cox and David Schwimmer have previously guest starred, leaving Jennifer Aniston as the only cast member who has yet to visit the series. Web Therapy is scheduled to return October 22.
