According to People Magazine on Tuesday, Ramona - who is promoting her new book, Life On The Ramona Coaster, opens up about her estranged husband, who cheated on her multiple times with his mistress Kasey Dexter while the two were still married. The blonde beauty finally pulled the plug on their marriage last summer.

She discussed their split in a new interview, explaining, "I think once I became a 'celebrity'... and I was in the public eye - I think that bothered him. It wasn't even that he 'checked out of the marriage,' but it was like became 'a different person.'"

She added, "There would be moments where he would be very warm and loving, and then other moments that he was really vicious and mean, and would bully me. It was like, 'who are you?' It was scary, it was very scary."

Ramona adds that the former couple don't speak anymore and only communicate through their lawyers.

"I don't recognize who he is today. That's the only way I can heal with it, because when he's across from me, he's not the man that he was two years ago. He completely changed," Ramona said, adding, "He became another person. He's another person."
