Actress Mila Kunis, who is dating Ashton Kutcher, attended his brother's wedding recently.
Kutcher's brother Michael Hightower tied the knot with Kate Jan 31 in front of family members and friends in St. Simon Island, Georgia.
A source who attended the nuptials told eonline.com that Kutcher looked "chill and comfortable" as he stood among five other men who wore simple white shirts and bow ties. Kunis, meanwhile, mingled among the guests and she "looked like part of the family."
Following the ceremony, a reception was held at the same private house and the guests spent the night in a cottage house.
"Overall, it appeared everyone had a great time," the source added.
