The "Curb Your Enthusiasm" actress will play a single Jewish mother and successful businesswoman who wants her son to have the best bar mitzvah ever, but ends up making the party all about her. Hines' episode is slated to air sometime in 2014.
The casting reunites Hines with star Robin Williams, who played her husband in the 2006 road trip comedy film "RV," which co-starred Will Arnett, Josh Hutcherson Kristin Chenoweth and Jeff Daniels.
"The Crazy Ones," executive produced by David E. Kelley, stars Williams as Simon Roberts, an executive at the Chicago advertising agency Lewis, Roberts + Roberts, who works with his tightly wound daughter and protégée, Sydney, played by Sarah Michelle Gellar. CBS gave the sitcom a full season order back in October.
"The Crazy Ones" returns on Thursday, Jan. 2 at 9/8 p.m. CT on CBS, while "Suburgatory" Season 3 premieres on Wednesday, Jan. 15 at 8:30/7:30 p.m. CT after "The Middle" on ABC.
