Matthew Perry And Courteney Cox On 'Go On': Sneak Peek At Reunion Episode (VIDEO)

NBC's long-awaited Monica (Courteney Cox) and Chandler (Matthew Perry) reunion will finally air this coming Tuesday (Mar. 26 at 10 p.m. ET).

So what can viewers expect from Cox's "Go On" appearance? A whole lot of grief.

In the clip above, Cox appears as a widow who is set up on a blind date with Perry's Ryan. When their server tells them happy hour has ended, Cox's character bursts into tears and says, "The other hours of my life aren't happy, why should this be any different?" And with that, she gets a free round of drinks and buffalo wings.

Both "Friends" alums have expressed their excitement over reuniting on the small screen again.

"Courteney Cox shooting Go On today..! She is fantastic, obviously. And my desire to show off in front of her is back in full swing!" Perry tweeted when the duo shot their episode back in February, while Cox tweeted "my first box husband," along with a photo of them together.

"Go On" airs on Tuesdays at 10 p.m. ET on NBC.
