Ashton Kutcher and Mila Kunis are planning to get married next July.

The couple, who got engaged earlier this year and are expecting their first child, have reportedly set a date for their wedding next summer, as they want to get acquainted with their baby girl before they tie the knot.

A source close to the former 'That 70s Show' co-stars told gossip website RadarOnline.com: ''The wedding will be next July. They want to focus on their daughter first and having it next summer seems logical.''

The 36-year-old 'Two and a Half Men' actor's family are very excited about his upcoming nuptials to the 'Black Swan' star, 30.

The insider said: ''Ashton's parents are very traditional and they love Mila. They got famous together, so she keeps Ashton grounded and vice-versa.''

The couple are eager to have a very small wedding, with just a small number of close friends and family members.

The source said: ''They won't have a big production but it will be elaborate. The wedding party will consist of the cast of 'That 70s 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 him and Ashton are like brothers.''

The couple, who started dating in 2012, also hope to have a big family in the future.

The insider explained: ''They both want a large family and want to start on their next kid shortly after they tie the knot. They are soul mates and know that they will be together forever.''

That last line though.

I don't wanna doubt celebrity couples, but something happens almost every time.
