The castmates of “The Real Housewives of Beverly Hills” are bringing some drama on and off the screen in the show’s third season and the latest episode, titled “She’s Gone Too Far” is no exception.

Castmates Adrienne Maloof and Brandi Glanville (the ex-wife of actor Eddie Cibrian who is now married to LeAnn Rimes) have not been fond of each other for quite some time now, but on episode 6 of the show, Glanville took things a step further by revealing a secret about Maloof and her now ex-husband, Paul Nassif. According to Wetpaint, Adrienne didn’t hear Glanville’s comment when she initially made it, but was informed by Kim Richards, who had.

The allegation was evidently so damning that it prompted Nassif, 51, to call Glanville a “b---h” before leaving the party with his wife, and sparked looks of horror from the other cast mates. Even more shocking, the show’s producers actually edited it out of the episode, only leaving in Glanville’s allusion. Instead, all viewers saw of the altercation was the fight leading up to Glanville’s bombshell along with her assertion that Maloof and Nassif were “lying” about their family.

In Maloof’s confessional after the fight, she accused Glanville of defaming her, saying, “What Brandi is saying is character assassination. Her lies have gone too far,” however she neglected to explain exactly what it was Glanville said.

According to the Huffington Post, Glanville’s big revelation, which was overheard on the set, was that Maloof used a pregnancy surrogate to have all three of her children with Nassif. Maloof, who is 51, has three sons, a 7-year-old and two 4-year-old identical twins, meaning that she would have been 45 or 46 at the time the twins were born, and there have been rumors that she used a surrogate to carry the children due to her age.

But Maloof patently contradicted those rumors during an episode two weeks ago, when she claimed that she had delivered both of her pregnancies via C-section, with Paul present in the delivery room. If the allegation is true, Maloof would be the second known cast member to have hired a surrogate, as Camille Grammer publicly acknowledged on the first season of the show that she and her ex-husband Kelsey Grammer used one to have their son and daughter.

Grammer, who has also admitted to suffering from severe Irritable Bowel Syndrome and has even recorded public service announcements to raise awareness about the condition, claimed that the disorder was the reason she used a surrogate. But despite Grammer’s transparency on the issue, Maloof has never before even hinted that she might have also used a surrogate.
