Hollywood actress Demi Moore has revealed that she regrets having threesomes with her ex, Ashton Kutcher.

"I wanted to show him how great and fun I could be," Demi wrote in her new book, Inside Out," according to Radar Online.

According to Demi, 2010 she saw media reports claiming Kutcher met a 21-year-old woman while bowling with her daughter Rumer Willis. She also claims that he cheated on her in their marital home while she was away filming a movie. When she finally confronted Kutcher, he threw their wild nights together back in her face.

"Because we had brought a third party into our relationship, Ashton said, that blurred the lines and, to some extent, justified what he'd done," she said, to "deflect blame."

Kutcher has not addressed his ex-wife's claims. He may be waiting to see what other tea she spills in the book when it drops on Sept. 24.
