Colin Farrell and Amelia Warner: 4 months
Actor Colin Farrell married a young actress, Amelia Warner, in a non-legal ceremony in 2002. Farrell even got Amelia Warner’s nickname, Millie, tattooed on his ring finger as a sign of his commitment. However, their marriage lasted only a few months. As Farrell commented later, the reason for their split was that they were both too young and the decision to marry was too fast. At that time, the actor was 24 and she was 19.
