After starring in season three of The Real Housewives of Beverly Hills, Marisa Zanuck will not return for the reality series' next season, she confirmed.

Zanuck told Celebuzz she "wasn't asked back" for season four of the Bravo show, adding, "It's as simple as that and I'm okay with it."

"Housewives was a once in a lifetime experience and I am grateful that Bravo gave me the opportunity to step into their crazy world," she said. "I have no regrets and nothing but love for the amazing viewers that were so kind to take time out of their day and reach out to me on Twitter and comment on my blogs. We will definitely keep in touch."

Adrienne Maloof and Camille Grammer confirmed individually that they also will not be returning to the show. An insider added that Faye Resnick turned down an offer to be a full-time cast member on the show and also decided to appear on any future episodes of the series.

Housewives star Yolanda Foster told reporters at OK! Magazine's So Sexy Party earlier in April that filming for season four has already begun. Taylor Armstrong will also return for season four and has already begun filming her scenes, a source told Radar Online. The insider added that Bravo producers asked Armstrong to come back for season four because it was hard to find replacements for Maloof and Grammer.

The mother-of-one will not have as much camera time in the upcoming season and will be featured as a "friend" of the cast rather than an "official housewife," a source told Starcasm.

Brandi Glanville's filming for season four may have been delayed because she was recovering from laser treatment she had on her face.

Casting rumors for season four of Housewives continue and the latest revolve around former model and mother-of-two Brenda Soleimani. The 40-year-old told the Beverly Hills Courier she was approached by Bravo producers to join the reality show's season four cast.
