Ashton Kutcher confesses he was only 'interested in sex' with Mila Kunis when they first started dating

Ashton Kutcher and Mila Kunis may be happily married now – but the actor revealed when they first started dating it was purely sexual.

After finding themselves both single in 2012 – Ashton had split from wife, Demi Moore, and Mila had ended her relationship with long-time boyfriend, Macaulay Culkin, the pair immediately bonded.

‘She’s like, “You’re not ready to be in a relationship” and I’m like, “I’m not ready to be a in a relationship,”‘ he told The Howard Stern Show this week.

What made their hook-up even more memorable, according to Ashton, was that their lives really were imitating their art.

‘It was funny because I’d just done this movie called No Strings Attached and she just did a movie called Friends With Benefits and we legitimately lived out our movies, which was virtually the same movie,’ he explained.

No Strings Attached starred Ashton and Natalie Portman and Friend With Benefits featured Mila and Justin Timberlake; both movies came out in 2011.

‘At the time, we were like, “OK, we have an agreement,”‘ he added.

‘I was smoking cigarettes at the time and I was still a smoker and she had quit smoking and she wanted me to like shotgun cigarette smoke so she could breathe it in. And I was like, “Well alright.”

‘And so I started doing this and gradually through the night, it got closer and closer and closer,’ he said.

Ashton added: ‘I think it was pretty mutual — it was kind of obvious that things were happening.’
