Ashton Kutcher and Mila Kunis appear to be one of Hollywood's most solid couples, but it all started as a casual hook up.
The pair first met as teenagers on the set of That '70s Show, where they played an on-screen couple.
Ashton went on to marry Demi Moore, while Mila had an eight-year relationship with Macaulay Culkin, before the pair reconnected in 2012.
"She was like, 'You’re not ready to be in a relationship' and I’m like, 'I'm not ready to be a in a relationship,'" Ashton revealed on The Howard Stern Show. "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."
The rom-coms, also starring Natalie Portman and Justin Timberlake, were both released in 2011.
"At the time, we were like, 'OK, we have an agreement,'" he added. "I think it was pretty mutual — it was kind of obvious that things were happening."
Mila and Ashton got engaged in 2014 and married in summer 2015. Together they have a two-year-old daughter Wyatt Isabelle and a six-month-old son Dimitri.
