Ashton Kutcher says that he found it “difficult” to like Bruce Willis because he used to sleep with his wife.

The Killers star admits he initially found it challenging to get along with his spouse Demi Moore‘s former husband, because he couldn’t stop thinking about how they used to have sex together.

“At first it was difficult. You think, ‘He’s the guy who used to sleep with my wife,’ but once you overcome the jealousy, which is just your own personal insecurity, it gets easier.”

The two men now get along brilliantly, and often spend time “hanging out” together with Demi and Bruce’s daughters - and Ashton’s step-daughters - Rumer, 21, Scout, 18, and 16-year-old Tallulah Belle. “People ask us, ‘How do you guys get on so well?’ Well, I don’t like everything Bruce does, and I’m sure he doesn’t think everything I do is great. But being with Bruce is normal to me now. We go scuba-diving, skiing, we hang out with the girls together, we watch movies, we talk about sport.”
