Brandi Glanville posted an apology on her Bravo television blog about the personal comments she made about co-star Adrienne Maloof in the latest episode of "The Real Housewives of Beverly Hills." 

When the episode aired on Monday, viewers were not sure what the personal secret was that Glanville publicized to the rest of the cast members. However, a source close to the show has since come out revealing that Glanville said Maloof used a surrogate for her three children.  

On Monday night, Glanville took to her blog and posted the following comments:

"I said something I shouldn't have said and I am sorry and I now regret it."

She continued: "I know, it's shocking right? My mouth gets me in a lot of trouble, but this time I've pissed off the wrong rich person...We all make mistakes, and if I could take this back I would. Trust me! I can't, so now I just have to deal. Boy is it going to be expensive!"

Glanville was called out on the show for making a comment that hit "below the belt," but she defended herself online by writing that when she is attacked, as she has in the past, she fights back, and hard. She wrote that it is "frustrating" to hear that Maloof or her representatives made false comments about Glanville or discuss her parenting skills, but when the lies involve her children, "like any good mother, ALL BETS ARE OFF!" she said.

Maloof has not commented on her own Bravo blog about the surrogate accusations.

The comments made on Monday's episode resulted in Maloof and her ex-husband, Paul Nassif, and Glanville getting into a heated argument at a business party attended by the other cast members. Curses were flying from both sides and Maloof threatened to sue Glanville for the defamatory accusations she made and publicized to others about her family.
