It was a rough third season of The Real Housewives of Beverly Hills for Adrienne Maloof -- and she doesn't want to relive it. The ladies of Bravo's hit reality series -- Maloof, Lisa Vanderpump, Brandi Glanville, Kim Richards, Kyle Richards, Taylor Armstrong plus newcomer Yolanda H. Foster -- were scheduled to tape the reunion special on Friday, March 1, but a source tells Us Weekly that Maloof isn't joining them.

Maloof, 51, decided to skip the reunion to attend a more important obligation with her kids, the source tells Us. (TMZ and RealityTea also reported on Maloof's absence at the taping.)

The reality TV starlet divorced husband Paul Nassif while season three filmed, and became single mother to sons Gavin, 9, and twins Christian and Colin, 6.

She also found herself at the center of many heated feuds with her cast members, particularly with Glanville, 40. "She doesn't need that kind of negativity in her life," the insider says.

Glanville, meanwhile, has been gearing up to settle scores with with her costars, tweeting Friday, "It's on like Donkey Kong!" 

The Drinking & Tweeting: and Other Brandi Blunders author infuriated Maloof after she revealed that the hotel mogul used a surrogate to have her twins; Maloof then sent a letter threatening legal action.

"The problem with Adrienne is, she uses other people to do her dirty work for her. She uses her chef [Bernie Guzman] and different people to say really negative things about all of us without getting her hands dirty," Eddie Cibrian's ex said on Anderson Live Feb. 15. "I don't know that a lot of people have turned against her, but she was pretty bad to Lisa, and she was horrible to me. I think everyone else is still kind of friendly, to be honest."
