As ironic as it may seem, exes "Two And A Half Men" actor Ashton Kutcher and "Ghost" actress Demi Moore recently attended the renewal of vows ceremony of the manager of singer Madonna.

Guy Oseary and wife model Michelle Alves renewed their vows recently in Rio de Janeiro, Brazil. The grand ceremony, which reportedly cost around $250,000, was attended by A-list stars, including "Fifty Shades of Grey" star Dakota Johnson, "Interstellar" lead Matthew McConaughey, U2 band member Bono, Kutcher, and Moore.

Former sweethearts Moore and Kutcher were reportedly in the same event, though there is no confirmation as to whether the two exchanged words. Paparazzi, however, caught a glimpse of Kutcher and Moore separately, as they both left the venue just minutes apart. Kutcher's wife, 34-year-old Mila Kunis, was absent during the reaffirmation of vows, as she was busy promoting her new film "A Bad Moms Christmas."

Moore, 54, and Kutcher, 39, announced in 2011 that they were going separate ways after being married for 6 years. "Marriage is one of the most difficult things in the world and unfortunately sometimes they fail," read the statement of Kutcher. "There are certain values and vows that I hold sacred, and it is in this spirit that I have chosen to move forward with my life," Moore's statement said.

An assistant alleged Kutcher of having sex with her on the night of his and Moore's sixth wedding anniversary, which was the reported reason for the split. Sara Leal, then 22, in an interview with the US Weekly said that she and the actor had an unprotected sex on Sept. 24, 2011.

The "No Strings Attached" actor got married to his "That '70s Show" co-star Kunis, 34, in July 2015. They have two kids, Wyatt Isabelle and Dimitri Portwood.
