Shortly before their eighth wedding anniversary in early July, Ashton Kutcher (45) is grateful on Instagram for his marriage to actress Mila Kunis (39). “I’m the happiest man in the world,” he writes about a photo of his loved one.

The picture shows a picturesque blue sea in front of a green island, in front of which a rainbow can just be seen. Mila Kunis stands under the colorful spectacle of nature, closes her eyes and spreads her arms. The actress is makeup-free, has her hair pulled back into a loose bun and wears a black button-down tank top. Kutcher also provides his post with the hashtag

Mila Kunis and Ashton Kutcher met on the set of US sitcom That ’70s Show, which ran from 1998 to 2006. However, they only became a couple in 2012 after Kutcher divorced Demi Moore (60) in 2011 after six years of marriage. He and Kunis then tied the knot in July 2015. Their daughter Wyatt was born in 2014, their son Dimitri was born in 2016.
