Ashton Kutcher may be happily settled into married life with Demi Moore now but he was a "serial dater" back in his bachelor days and he wants to apologize for it. The former "Punk'd" host is making a "dirty little movie" to apologize to the girls he had hurt back then.

The 30-year-old actor confesses that he had a "serial dating period" before marrying his 45-year-old wife and he wants to make up for all the pain he had caused his ex girlfriends. He says that because of his fame and looks, he had been "pretty abusive to a lot of people."

And now he wants to make amends by making his next movie where he will be a bachelor a la Alfie.

He says, "It's about a guy who's a dating machine - he sort of seduces women for financial gain without officially being a gigolo. It's a pretty dirty little movie."

"It's honest, and in this case that honesty is kind of brutal."

He adds, "This movie is kind of my way to say I'm sorry to a lot of girl I may have hurt by not being respectful."

Kutcher also reveals to Vman magazine that he and Moore "treat each other with reverence" and that they "share a really unique partnership."
