Adrienne Maloof's secret regarding her family returns as the storyline on episode nine of "The Real Housewives of Beverly Hills" that airs Monday, Bravo spoilers revealed.  

Brandi Glanville's feud with Maloof is discussed at a gathering among the other women. Yolanda Foster is confused about what Maloof is suing Glanville for exactly but Kyle Richards explains its about intimidating her. Lisa Vanderpump, who is a friend to Glanville, thinks Maloof is using her wealth and status to scare Glanville over the family secret, which has yet to be revealed on the show.

Kyle's husband, Mauricio, tells Glanville she did not need to say the secret about Maloof's family to other people and Glanville gets defensive, admitting she did not have to but felt compelled to do it for reasons she did not explain. Discussion of the lawsuit also brings up issues both Kim Richards and Taylor Armstrong faced and the two women as a result get into a heated dispute.

First mention of Maloof's family secret was brought up in a December episode of the show. While the reality television star has not said what the secret is, a source said that it was about Maloof using a surrogate for her three children. On the after show with Andy Cohen, former "Housewives" cast member Camille Donatacci Grammer was a guest and when a viewer called in to ask about the big secret Glanville revealed, Grammer did not go into details about but did say that it was something extremely personal about Maloof's children. 

When Vanderpump addressed Glanville about making the comments in a following episode, Glanville said more than once about Maloof "you don't know what she's done to me," though she would not go into further details. 

Glanville posted an apology on her Bravo blog about the personal comments, saying "I now regret it" and "if I could take this back I would." She was criticized for making a comment that hit "below the belt," but she defended herself online by writing that when she is attacked she fights back, and hard. 

"Real Housewives of Beverly Hills" season three airs Mondays on Bravo at 9 p.m. Eastern Time.
