RHOBH Brandi Glanville cheated on Eddie Cibrian first? Denies cheating rumors and says 'not in my DNA'

Real Housewives of Beverly Hills star, Brandi Glanville is coming clean about her own infidelities while she was married to Eddie Cibrian. In her new tell-all, Drinking & Dating: P.S. Social Media Is Ruining Romance, Glanville admitted that she cheated on the actor.

"Last year," Glanville writes, I discovered, much to my surprise, that I was an unfaithful wife."

According to Us Weekly, Glanville allegedly cheated with former NBA star, Rich Fox and Pink Taco millionaire Harry Morton while still married, but Glanville claims that the reports were false and insinuated that the rumors were planted by LeAnn Rimes.

 "Who on earth could have anything to gain by leaking false information about an alleged affair seven days before the tell-all book about my philandering ex and his mistress [Glanville's Drinking & Tweeting] hit bookstores?" she asks. "Hmmm. You tell me."

"To top that, my 'affairs' were apparently with former NBA player Rick Fox, who I don't believe I've ever met," the Real Housewives of Beverly Hills star writes, "and restaurateur Harry Morton. Knowing what I do now about what a sham my marriage was, I may have welcomed dating either one of these eligible bachelors, but it just wasn't true."

Glanville did admit that she had flings before the divorce was finalized but denies any affairs, "Did I ever have an affair before that? No. Not ever. That's just not in my DNA."
