According to the Hollywood Reporter, Moore will join the show in recurring guest role as the retired mother of Brooke Shields' character, Wendy Healy. The writers of the series are reportedly incorporating Moore's history as a pioneer for single women in the workforce into her role. Moore joins the series on the season premiere Sept. 24.

Based on the novel penned by "Sex and the City" author Candace Bushnell, "Lipstick Jungle" stars Brooke Shields (Wonderful Town, "Nip/Tuck"), Kim Raver (Holiday, "24") and Lindsay Price ("Beverly Hills, 90210").

"I'm fortunate to have had a front row seat to the evolution of working women on television," Moore told The Hollywood Reporter. "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."
