Casting Couch: Lipstick Jungle Gets Moore, Showtime for Wentz, Disney for Duhamel

Mary Tyler Moore signs on for multi-episode arc of NBC's glossy hit when it returns Sept. 24

Lipstick Jungle is trying on a new shade of star power this fall.

TV icon and seven-time Emmy winner Mary Tyler Moore has signed on to star in several episodes of the glossy NBC series when it returns for its second season Sept. 24.

Moore will play Joyce, a retired high-powered exec and mother of Brooke Shields' character, who challenges her daughter's notion of having it all, professionally and personally.

"I'm fortunate to have had a front-row seat to the evolution of working women on television," Moore said in a press release. "It's been great fun to watch the strong female characters of Lipstick Jungle go at it week after week. I absolutely adore Brooke and I'm delighted to be a part of a show which is so well written."

She's gonna make it (better) after all.
