The Real Housewives of Orange County's Tamra Barney denied cheating on her husband Simon during Bravo's Watch What Happens Live Thursday night , as the blonde stunner broke her silence on the details surrounding her pending divorce.
In response to Simon’s January 6 court paper claims that Tamra “has been verbally abusive and has committed acts of disloyalty and adultery,” Barney said, "No, I do not cheat on my husband."
Barney -- who said she had been mum to avoid making "this a public issue" or media "circus" -- told Bravo she believed Simon accused her of cheating because he knew with her celebrity status, the story would spread like wildfire.
Tamra said that after a New Year's Eve fight between her and Simon, she decided to leave her hostile household on a "trial separation" basis. The blond beauty said she "had to leave," as she couldn't continue living in 2010 the way she did in 2009.
Tamra and Simon have been married for nearly 12 years and have three children, ages 11, 9 and 4.
