'Go On': Lauren Graham checks in on Matthew Perry

matthew-perry-lauren-graham-gi.jpgAn old friend of Matthew Perry will guest on his new show "Go On" later this season.

No, not that kind of "Friend." "Parenthood" star Lauren Graham, a real-life pal of Perry's, will appear in an upcoming episode, EW reports.

Graham and Perry dated briefly about a decade ago and have remained friends ever since. She also guested (as herself) on a couple of episodes of Perry's series "Studio 60 on the Sunset Strip" in 2006.

In "Go On," Graham will play a friend from college and former co-worker who drops in on Perry's Ryan King as he continues to deal with the loss of his wife.

There's no airdate for Graham's episode yet. "Go On" airs at 9 p.m. ET Tuesdays on NBC, an hour before "Parenthood."
