Adrienne Maloof: Brandi Glanville 'Crossed the Line'
12/12/2012 AT 05:15 PM EST
The bombshell, which never actually revealed on Monday night's show, has created speculation among viewers and online that Glanville, 40, may have revealed information about Adrienne's marriage to Dr. Paul Nassif, 50, before their divorce over the summer.
Maloof is now firing back against Glanville.
"She seems to be addicted to attention and keeping herself relevant, and I think that’s her goal," Maloof tells PEOPLE. "Her antics have crossed the line for me."
Maloof refuses to discuss what Glanville may have been alluding to, saying she wants to protect her children.
"I keep my children out of the limelight and I don’t speak about my children," Maloof says. "It's something you don’t even want to address. They deserve to have their privacy, and I am giving my children their privacy. As a mother I do what I can to protect my children and my family."
In the episode on Monday night, Kim Richards informed Maloof and Nassif about Glanville's comments, and the show concluded with a fiery confrontation as Nassif called Glanville's allegation "defamatory" while his wife joined in on the screaming fight.
"You lie," Maloof repeatedly said to Glanville during the angry altercation on TV.
Up to this point in the season, which filmed in the spring, Nassif and Maloof's marriage appeared solid. In reality, word that the couple was splitting first surfaced in July when Nassif filed for legal separation.
Subsequently, after much rancor and allegations of physical and verbal abuse, the pair settled their divorce amicably in early November.
As for Glanville, she now says she's sorry for what she said.
"I said something I shouldn't have said," she blogged on BravoTV.com, "and I am sorry and I now regret it," she wrote. "My mouth gets me in a lot of trouble, but this time I've p––d off the wrong rich person. ... No one is perfect. We all make mistakes, and if I could take this back I would."
