Eddie Cibrian took a bashing from wife LeAnn Rimes’ ex-husband, Dean Sheremet, who said he was completely blindsided by their affair.

Sheremet was married to LeAnn Rimes for seven years before divorcing in 2009, after he found out his wife was having an affair with then-married Eddie Cibrian.

In an interview with Nat’s Next Adventure, the former backup dancer spilled his guts on the affair and the aftermath.

Sheremet said things were already on shaky ground before the affair commenced.

“I felt like I was never having my needs met so there was fighting,” he said. “And I was so intertwined in managing her career that I didn’t know how to make the distinction between husband and boss, husband and partner, husband and manager… I was husband, father, friend, lover, manager. There were so many hats and I didn’t know what hat to wear when.”

Unfortunately, I think the business ended up destroying us,” he said. “That passion for our marriage wasn’t there. The person that I needed to be, the person I should have been, I wasn’t. I wasn’t the person she came home to and unloaded on. And, then, of course, I was thinking, I haven’t done what I’ve wanted to do in over eight years.”

Because of his role in LeAnn Rimes‘ life, he said he never expected her to stray.

“Never in a million years did I think something like that would have happened,” he said. “The need for me in her life was so strong. There were things she couldn’t do without me. She had her own phone but never used it. People would call me to get to her. Everything went through me.”

Although Sheremet said he thought Eddie Cibrian was a “good looking guy” and “charming,” he never felt threatened.

“I just remember being like, ‘Oh, God, just another one of those Hollywood pretty boys,'” he remembered. “If you’re in a room with him, he’s probably one of the most charming people you’ll ever meet. But I wouldn’t trust him as far as I could throw this f**king table. He just felt like one of those guys from the beginning. A total schmoozer. Very Hollywood. I never bought his shtick. But I wasn’t worried.”

Sheremet shared the exact moment when he realized the two were intimate.

“There was this bar that everyone hung out at after set and I remember coming down the stairs and seeing the two of them shooting pool together,” he recalls. “I could just tell by the body language that everything had changed. She’s shooting pool, shooting tequila, in a tight tank, tight jeans, over the knee boots and she’s standing across from him, playing with the pool cue. All of a sudden, there was a huge shift. My stomach dropped. I literally felt like I got hit.”

“I totally felt foolish,” he conceded. “I felt like this pathetic husband hanging around. I was very aware of how others were looking at me. … I was like, ‘Why am I here? I don’t need to be babysitting someone on set.’ Even though in my brain, I was like, ‘I’m seeing this happening, I should be here and do something.’ But I wasn’t going to be able to stop anything that happened. And I wasn’t doing anyone any good.”

Sheremet said the backlash for his ex has been long-lasting.

“The dumbest thing she ever did for her career was divorce me, because we were such a good team. The last hit song she had was when she was with me,” he said.
