The actress made the revelation during a recent interview with Howard Stern, adding that there had been no romance between herself and the actor until two years following the end of their sitcom.

Speaking during the interview, Kunis said:

"I don’t even know If I’m supposed to tell this story, I might get in trouble for this, well, whatever. We ran into each other out and about at an awards show.

“So I see this guy and I see his back. And he’s really tall and I’m like, who’s that tall guy? And I’m wearing this big poofy dress and I look ridiculous and then he just turns around and it’s literally like if we were in a movie the music would start playing and the violins would go. I think he, for the first time, ever took my breath away. I was like, f*ck he’s good looking.”

Kunis who is pregnant with her second child with Kutcher, went on to reveal that he had later invited her to his house-warming party with plans of hooking her up with a friend of his but all that quickly changed.

“When I was single I was so adamant about, as stupid as it sounds, never staying over at a guy’s house.

“I was like, peace I’m out, and he was like, you’re not leaving.”
