Mila Kunis and Ashton Kutcher are married, reports say

Ashton Kutcher and Mila Kunis, who first met on the set of That '70s Show in 1998, have finally tied the knot, People Magazine said quoting an unnamed source.

Kutcher,37, and Kunis, 31, played a couple on the popular sitcom, and began dating in real life around 2012, when Kutcher broke up with ex-wife Demi Moore.

They have a daughter, Wyatt Isabelle, who was born last October.

They were engaged early last year.

People Magazine reports that the couple married secretly on the fourth of July weekend.

She said in W magazine's August issue: "My first real kiss ever was with him on the show. We all get movie star crushes.

"I'm marrying mine."
