Holly Marie Combs, Brooke Burns and Rochelle Aytes have signed on to star in Lifetime's drama pilot "Mistresses."
Additionally, Michael Weaver and Mary Birdsong have joined HBO's half-hour pilot "Suburban Shootout," directed by Barry Sonnenfeld.
Based on the BBC series, "Mistresses," from Fox 21, revolves around a quartet of thirtysomething women who have been friends since college.
Combs ("Charmed") will play Jane, who gave up her career to be a stay-at-home mom. Burns ("Miss Guided") will play Shannon, an outspoken and sharp attorney. Aytes ("Drive") will play Ava, a bright and spunky soap star.
"Suburban," which also is based on a British series, is a dark comedy about Rebecca (Judy Greer) who escapes the city for suburban bliss only to find herself caught between two rival gangs of homicidal housewives as they vie for control of their idyllic town.
Weaver ("Notes From the Underbelly") will play Rebecca's husband and new chief of police of the suburban town. Birdsong ("Reno 911!") will play a member of one of the gangs.
