Safe to say these two are officially expert wedding guests—so when will they take their own trip down the aisle?!
The Two and a Half Men stud's sibling wed Kate Hightower at a private home in front of the couple's closest family and friends, who were all present during the intimate affair to celebrate the lovebird's nuptials.
According to a source, Kutcher seemed very "chill and comfortable" during the "I do's," and, although it's unclear if he served as the best man, he was seen standing with a group of five guys dressed in simple white shirts and bow ties.
Meanwhile, the insider added that Mila "looked like part of the family" as she enjoyed time with her man's relatives.
After the ceremony, the reception was held at the same location, a private home, where guests spent the night in a cottage house.
"Overall, it appeared everyone had a great time," the source added.
Mila and Ashton were seen at the airport on Sunday, Feb. 2, returning from the weekend's festivities while looking like the perfectly coordinated couple in their matching navy blue jackets.
In December, the former That 70s Show costars made headlines after they attended the nuptials of Mila's brother Michael in St. Petersburg, Fla., where the Ted star served as a bridesmaid.
Kutcher attended the intimate "I do's" as the Black Swan beauty's date, where according to a source, the couple looked "totally in love and inseparable at the wedding."
"Ashton was very supportive of Mila and happy for the family. He was joking around with Mila's brother and they invited him to come and pose for family pictures with the bride and groom after the wedding," the source said. "They rarely left each other's sides and were always holding hands and whispering to one another. Ashton let Mila do her thing but always was right there at her side."
Just a few months prior, the duo sparked engagement rumors of their own when Kunis stepped out wearing a simple gold band on that finger.
She sported the same jewelry piece to her brother's wedding, but at some point during the ceremony, moved the ring to her right hand.
