Grace and Frankie just got a fourth season. And Lisa Kudrow is getting in on the fun.

Always keen to prove that getting older doesn’t mean slowing down, the ladies of Grace and Frankie are returning for a 13-episode fourth season with a special guest star, EW has learned.

If you thought it couldn’t get better than starting a vibrator company for the more mature lady, think again. Netflix is further shaking things up with the addition of Friends star and Emmy Award-winning actress Lisa Kudrow, who enters the fray as pink-velour-tracksuit-wearing manicurist Sheree. As a longtime acquaintance of Grace, she (of course) manages to cause a riff or two between the besties during her guest-starring arc. But in the first look photo above, the trio is all smiles as they deep their fit into the pool.

The Netflix series, the third season of which premiered on March 24, follows Grace (Jane Fonda) and Frankie (Lily Tomlin) as they become reluctant yet close friends after their husbands leave them later in life to start a relationship with one another. Marta Kauffman, who co-created Friends alongside David Crane, also co-created the Skydance Television-produced series and serves as an executive producer.

Get ready for more technological hiccups, beach-house boozing, and general geriatric hilarity when the ladies return for season 4 in 2018.
