LOS ANGELES -- CBS says popular sitcom star Sean Hayes is joining the cast of its comedy "The Millers" as a series regular.
Hayes, who is from Glen Ellyn, will play the new best friend of the character played by Margo Martindale and a new source of friction for her son, played by Will Arnett, CBS said on Tuesday.
Hayes is best-known from eight seasons on the sitcom "Will & Grace." Last season he starred in the comedy series "Sean Saves the World."
"The Millers," which premiered last fall, is a family comedy also starring Beau Bridges and J.B. Smoove. Its second season begins Oct. 30.
