Ananova:

Colin Farrell says he always wears his lucky underpants when he starts a new film - because they never fail to bring him good fortune.

The Phone Booth star - who has been linked with leading ladies Angelina Jolie and Rosario Dawson - refuses to start work until he's donned the shamrock-design boxer shorts and has promised to keep up the tradition throughout his career.

According to Teenhollywood he explains, "My brother gave them to me. They're my lucky charm.

"If I don't have them, I won't come out of the trailer. They're starting to get a bit old now but I could never part with them."

Farrell is currently filming The New World which is due for release next year.
