Lauren Graham to Guest Star on Go On

Two NBC worlds are set to collide.

Entertainment Weekly reports that Lauren Graham will pay a visit to Go On in the near future, guest-starring on long-time friend Matthew Perry's new sitcom as a former co-worker of the Ryan King.

Go On premiered September 11 and focuses on Perry as a sports talk radio host and a member of a "life change" support group. It has enjoyed strong ratings out of the gate for NBC.

Graham, meanwhile, stars on the perennially underrated and under-appreciated Parenthood. Seriously, it's really, really good.
