Actor Billy Bob Thornton has warned young couples not to marry too young. The Monster's Ball star has wed five times, including a three-year union with actress Angelina Jolie, but each marriage ended in divorce and he is convinced he was too inexperience to handle the responsibility of family life. His first wife was Melissa Lee Gatlin in his early 20s and they had a daughter, but Thornton admits he was too young to care for his family. He writes in Britain's The Sun newspaper, "I should not have married and become a father so young. It is not fair on your wife and kid, because I still had so much to do. And perhaps I never did learn the lesson on marriage since I've been married five times."
