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.”
