The former 'Real Housewives of Beverly Hills' star split from her husband in July 2009 after it emerged he had had an affair with his 'Northern Lights' co-star LeAnn Rimes - who he is now married to - and has admitted she had suspicions as soon as she saw them on the set of the television movie together.

Speaking to Dr. Darcy Sterling on 'Famously Single', she recalled:

"I trusted him completely and fully. Then I went to visit him on a movie set and for the first time I felt like something was going on with the person that he was acting with.

"That morning I get a call from a bitchy mom that I'm not really friends with and she's like, 'Have you seen the cover of US Weekly?'

"I go to the store, get the magazine - panic attack, crying. It was on Access Hollywood, Extra... It's on every cover of every magazine. It's there. It's real. I laid on my closet floor and just sobbed."

Following the split, Brandi, 44, fell into depression but felt she had to keep it together for the sake of her and Eddie's sons, Mason, now 13, and Jake, now 13.

She added: "I had a couple of years of depression. I started drinking too much. I had to up my antidepressants and I cried all day every day.

"I lost too much weight. But I had to take care of my two kids. It wasn't about me any more."
