Paul Carafotes, an actor, has spoken out about his alleged affair with Demi Moore, who he claims climbed through his kitchen window for a night of “steamy s^x” with him just hours before marrying her first husband in 1981.

The pair had been having an affair for months behind Demi’s rocker fiancé Freddy Moore’s back.

Paul says their indiscretions culminated with Demi sneaking out of her own bachelorette party to visit his Hollywood apartment on the 4th floor, clutching a bottle of Dom Perignon champagne only hours before marrying Moore.

Paul spoke to DailyMailTV about the affair and the circumstances leading up to it, stating that Demi had pursued him persistently, and he had almost turned her down on the night of the affair because he was tired.

However, he eventually relented and offered to let her climb the fire escape to his apartment through his kitchen window, which she did.

He recalls, “I had worked 18 hours, I was tired, and Demi didn’t work that day. I was sleeping, and the phone rang.

“It was her, and she wanted to come over and see me. And I just said, ‘Ah, you know, that’s probably not a great thing to do right now. I’m tired. I’m in bed.’

“I hang up the phone, and she called again; she was persistent.

“Then I finally said, ‘look, uh, if you want to come over, I’ll open the kitchen window.

“You can climb the fire escape; I’m four flights up. If you want to do that, then you have at it.’ I went back to sleep.

Despite initially being hesitant, Paul said he was shocked when Demi turned up at his apartment with a bottle of Dom Perignon and said, “let’s do this, let’s party.”

Paul said he was impressed by her wild side and decided to go along with it.

“The next thing I knew, she was standing there with a bottle of Dom Perignon, standing over my bed, saying, ‘let’s do this, let’s party.’

“I was shocked; she was wild. What’s a red-blooded boy supposed to do? I had a buddy of mine staying with me over from Boston; he woke up and he was like, ‘Hey, aren’t you getting married tomorrow? Are you Catholic?’

She said, ‘Sure. Yeah,’ and he went back to sleep,” he said.

According to Paul, Demi climbed back out of his window and returned to her bachelorette party, and the next day, she married her first husband.

Paul said that he did not expect Demi to take him up on his offer to climb the fire escape but thinks she just wanted to have a last hurrah before getting married.

“I think she just wanted to have a last hurrah before she got married. She wanted to have some fun, she was young, she was a kid.

Maybe she wanted a last throw down and then she was going to be the good Catholic girl, I don’t know,” he said.

The 60-year-old actor says he has kept the affair under wraps for almost 40 years but was prompted to speak out after being outed as her former lover in Demi’s tell-all memoir, Inside Out. In the book, Demi revealed that she was unfaithful to Freddy the night before they got married.

“The night before we got married, instead of working on my vows, I was calling a guy I’d met on a movie set,” she wrote.

“I snuck out of my bachelorette party and went to his apartment.”

“Why did I do that?” Moore – whose father Danny Guynes committed suicide months earlier in October 1980 – wrote.
