Hilty will play Liz, Sean’s long-time friend and co-worker who is a former therapist. She replaces Lindsay Sloane, who played the role in the pilot.

Hilty most recently played aspiring Broadway star Ivy Lynn on "Smash." Her stage credits include 9 to 5, Gentlemen Prefer Blondes and Wicked.

In addition to Hayes and Hilty, the cast of "Sean Saves The World" includes Linda Lavin ( The Lyons, Collected Stories), Thomas Lennon (“Reno 911") and Echo Kellum (“Ben and Kate").

"Sean ( Sean Hayes, 'Will & Grace') is a divorced gay dad who juggles a lot — his successful but demanding career, offbeat employees, pushy mom Lorna ( Linda Lavin, 'Alice'), and weekends with his teenage daughter, Ellie (Sami Isler)," press notes state. "So when his 14-year-old bundle of joy moves in full-time, it's a whole new world. From keeping his boss happy, his employees motivated and enduring his mother's tactless 'advice' to raising a smart, grounded and healthy kid, it's going to be a growing experience, to say the least."

Hayes received a Tony Award nomination for his performance in the 2010 revival of Promises, Promises and hosted the 2010 Tony Awards. Hilty and Hayes previously worked together on "Smash," where Hayes guest-starred as a Hollywood actor making his Broadway debut.
