The Ted star looked stunning in a pink dress as she served as a bridesmaid for her brother Michael Kunis's wedding in St. Petersburg, Fla. Saturday, with Kutcher on hand for support.
"Mila wore a gold band on her engagement ring finger but it didn't have a diamond, just a simple gold band similar to a wedding band," a source told E! News. "Mila was very happy for her brother and his wife. During the ceremony, she stood at the altar and seemed very focused on the vows."
But while Kunis has been spotted multiple times with that gold band on that finger, at some point before hitting the aisle she moved it to her right hand.
