Mila Kunis & Ashton Kutcher
Mila Kunis and Ashton Kutcher have a different love story than most of the ones on this list. They met while filming That 70s Show and played each other’s romantic interests on the show. However, the couple didn’t start dating in real life for another fifteen years! Despite meeting in 1998, the pair didn’t have their first off-screen kiss until 2012. The couple got engaged in 2014- 16 years after first meeting each other. They welcomed a daughter later that year and tied the knot in 2015.
