Black Eyed Peas singer Stacy Ann Ferguson legally changed her name to Fergie Duhamel after a Los Angeles judge signed off, TMZ reported. The judge gave the approval Friday for the singer to change her last name to that of her husband of five years, actor Josh Duhamel. She also changed her first name because she said no one ever calls her Stacy. In order for the change to be approved, Duhamel had to post a notice in her local newspaper for four weeks before the judge gave approval.
