After revealing to her friend and co-star that her husband had been cheating on her for a whopping eight months, Beador revealed the woman, who has not yet been identified, actually befriended her during their affair.

"It was a long time and a lot of lies," Beador told Gunvalson, according to a report by E! News on Tuesday. "I became friends with her when it was going on, which I think is demented and sick. It's such a big form of betrayal. It's so f—ked up."

In her Bravo blog, Beador opened up about her friendship with Gunvalson, as well as her support throughout the last several months.

"When David left me and moved out last June, Vicki dropped everything and took me to dinner to be there for me. I will never forget that because it was absolutely the worst day of my life," she wrote. "Never in my wildest dreams did I think that my husband was having an affair. What made it so difficult for me was that his mistress infiltrated my life, befriended me, and vocally displayed an interest in my marriage... I thought I was gaining a friend, but she was basically acting, only interested in gathering information for the benefit of her affair with my husband."
