Jane Fonda and Lily Tomlin will star in the new Netflix series Grace and Frankie, the streaming service announced today. The show is a half-hour single-camera comedy written and created by Marta Kauffman (Friends) and Howard J. Morris (uh, Sullivan & Son), and it will have a 13-episode first season. Fonda and Tomlin will play longtime rivals who are stunned when their respective husbands announce they are in love with each other and plan to marry. "The women find their lives both turned upside down and to their dismay, permanently intertwined. Eventually, to their surprise, they find they have each other," says the official description. The show will premiere in 2015, and if there's any justice in this god-forsaken universe, Dolly Parton will appear on an episode to complete the 9 to 5 trifecta.
