Colin Farrell doesn't care if he is single forever. The 40-year-old actor - who has dated a string of famous women including Britney Spears, Angelina Jolie, Amelia Warner and Demi Moore - insisted that he is happy being alone and doesn't need a relationship to feel validated. Speaking to the newly launched Loaded website, he said: "I don't have any pressure at all about being single. I'm fine as a single man. I believe in relationships and marriage and people sharing their lives. But marriage isn't for everybody. I believe some people need to be single their whole lives, whether through choice or lack of fortune. I don't believe in any one way." However, despite being single for the past four years, Colin - who has sons James, 12, and six-year-old Henry from previous relationships - isn't against a relationship but he doesn't want a partner who reminds him of himself. He said: "I wouldn't look for any quality of mine in anyone else. I'm trying to get away from myself. Jesus! There's no part of me that interests me, excites me or gets me off enough to look for it in somebody else."
