By now, fans of The Real Housewives of Beverly Hills know that Marisa Zanuck, a Housewives ‘friend’ from Season 3, won’t be returning to the show.

I wasn’t asked back,” Marisa recently told Celebuzz. “It's as simple as that and I'm okay with it.”

But a source close to the show tells us that behind the scenes, Marisa’s plenty P.O.’d.

“She felt that she put it all out there — her marriage, her family — and tried to stir up drama, so she doesn’t get why they don’t want her back.”

In truth, the same source explains that it just wasn’t enough. “At the end of the day, she just wasn’t as interesting as producers had hoped. Yolanda, the other newcomer, really made waves. Compared to her, Marisa just seemed rather boring.”

“She also didn’t really connect with any of the other women except maybe Kyle and Adrienne,” the source adds. “And with Adrienne not returning, that only leaves one cast member she actually made an impression on. When it comes to casting, producers look for a truly polarizing personality and they didn’t feel they had found it in Marisa.”
