Michael Lohan got nothing but trouble in his relationship with ex Kate Major, but it turns out he’s a womanizer that had a mistress on the side, and RadarOnline.com has video of her talking about their relationship.

A woman named Kris appeared on Dr. Drew's Lifechangers and revealed that she started seeing Michael in June and thought they were exclusive saying, “He told me that he loved me.”

“Did you think you were in an exclusive relationship?” Dr. Drew asked Kris.

“Yes. He told me that we were. He told me that he loved me. He introduced me as his girlfriend…whenever he would talk about her [Kate] to me, he would bash her. Say she was crazy. 'She's insane, I just wish she would go away, I want her out of my life,'” Kris said.
