ICYMI, Mila Kunis' PDA For Ashton Kutcher Tends To Be Pretty One-Sided

Mila Kunis and Ashton Kutcher certainly took their time making things official, but four years since tying the knot and two kids later, it’s looking like it was well worth the wait.

Quick refresher: The couple met on That '70s Show in 1998, where their characters, Jackie and Michael, dated. In fact, because they played love interests, 19-year-old Ashton was 14-year-old Mila’s first kiss. Seems like a natural way for sparks to fly, right? Well, it would have been, if not for the age gap that Ashton described as “really weird.” Back then, their offscreen relationship was something more of a big-bro/little-sis situation, in which Ashton would help Mila with her chem homework. (Aw.)

Years later—as in over a decade later, in 2012—after Ashton married and separated from Demi Moore and Mila called it quits with her long-term boyfriend, Macaulay Culkin, the two reconnected at an awards show and started hooking up. As objectively hot as I can safely say that was, Mila and Ashton got over it pretty quickly and decided to DTR.

Since then, despite making only a few red-carpet appearances as a duo, Ashton and Mila have become poster children for matches made in primetime television. But when so much of a relationship is under wraps, how can you guarantee it's a sure thing?
