Happy Birthday, Ashton Kutcher! So many fans have grown up watching the actor and funny man mature over the years. From his days on That ’70s Show to his latest role as a doting father of two and husband of his former ‘70s Show co-star Mila Kunis, 37. These two truly have a storied romance. Although they met on the set of the popular early 2000’s series, it took quite some time for the pair to turn their longtime friendship into something so much more.
