The Captain America: The Winter Soldier star reportedly married Sheletta Chapital, the mother of his two sons, in the Dominican Republic in December (14).

MACkie flew his longtime partner and around 150 guests out to the Caribbean destination for the wedding while he was there filming new movie Our Brand Is Crisis with Sandra Bullock.

A source tells New York Post gossip column Page Six, "It was low-key and super-relaxed. They had a welcome dinner. We golfed and drank. They went on a honeymoon soon after."

The couple has known each other since they were children and dated on and off since they were at school.
