'Go On': Lauren Graham Will Guest Star On Matthew Perry's NBC Sitcom

Watch out, Jason Ritter: Lauren Graham's hanging with her ex Matthew Perry these days.

According to EW, "Parenthood" star Graham will guest star on NBC's "Go On" alongside Perry. Mimicking real-life, Graham will play an ex-girlfriend of Perry's character on the series.

"Go On" centers on Ryan (Matthew Perry), a sports radio host with a funny guy persona who enters a support group after the sudden death of his wife.

Meanwhile, Graham is busy playing the newly-engaged Sarah Braverman on NBC's "Parenthood," for which her on-screen fiance Mark Cyr (Ritter) earned an Emmy nod.

"He's the most wonderful guy and such a wonderful actor," Graham said of Ritter on "The Tonight Show With Jay Leno." "We feel proud, as if we're a small Olympic country who got one guy who got a medal. We got our one athlete in."

Catch "Go On" on airs on Tuesdays at 9 p.m. ET on NBC.
