Matthew Perry, who played Courteney Cox's husband in Friends, is all set to guest star on her show Cougar Town.
Cox has already made a guest appearance on Perry's now-cancelled NBC comedy Go On and he is returning the favour by making an appearance on her TBS comedy, reported Us magazine.
The Friends stars have been reuniting off and on. Perry and Lisa Kudrow appeared on an episode of Jane Lynch's summer comedy game show Celebrity Game Night while Jennifer Aniston and Kudrow also guest starred on Cougar Town in 2010.
Perry, 49, and Cox, 44, starred on Friends from 1994 to 2004. They played on-screen spouses Monica Gellar and Chandler Bing on the 10-season hit sitcom.
