Mila Kunis, Ashton Kutcher to wed in July 2015

LOS ANGELES, July 31 (UPI) -- Mila Kunis and Ashton Kutcher will reportedly marry in July 2015.

A source tells RadarOnline the wedding will take place next summer to allow the couple time to "focus on their daughter." Kunis is pregnant with their first child, and is expected to give birth in the near future.

"They won't have a big production but it will be elaborate," the insider says of the wedding. "The wedding party will consist of the cast of That 70's Show as they are all very close. They still hang out with the original cast all the time. Most likely Danny Masterson will be the best man because [he] and Ashton are like brothers."

"They both want a large family and want to start on their next kid after they tie the knot," a different source tells the website. "They are soul mates and know that they will be together forever."

Kunis and Kutcher met on the set of That 70's Show, but did not begin dating until April 2012. The pair confirmed their relationship in March 2013, and became engaged in February this year. Kunis announced her pregnancy in May, and the couple may name their daughter after Kutcher's mother.
