Long live the Bings! Nine years after the Friends finale in 2004, Courteney Cox and Matthew Perry -- a.k.a. Monica Geller and Chandler Bing -- are set to reunite onscreen, The Hollywood Reporter says.The Cougar Town actress, 48, is guest-starring on an April episode of Perry’s freshman sitcom, Go On, which features the former Friends actor as a sports talk radio host who finds comfort and several eccentric new pals in a support group after his wife’s death. Cox will play a new love interest for her former TV husband.The mini Friends reunion is one of many for the actress, who made a cameo on Lisa Kudrow’s Showtime series Web Therapy and has invited her former co-stars to appear on Cougar Town and on Dirt, the FX show she did after Friends. (BFF Jennifer Aniston guest-starred on both; Kudrow did an episode of the former during its run on ABC.)
