Aaron Johnson has been named the best dressed man in showbiz. The Kick-Ass actor beat fashion stalwarts including David Beckham and Tom Ford to the top spot of the GQ annual Best Dressed list of 2010, and removed Twilight star Robert Pattinson from the number one spot.

British actor Douglas Booth, who has appeared in campaigns for luxury fashion house Burberry, came second in the list, while A Single Man star Nicholas Hoult was third. David and Victoria Beckham's eight-year-old son Romeo was among the notable new entries on the list, coming in at 26, just 10 places behind his father.

Prince William came in at 27 and was hailed by rapper Pharrell Williams for his unique look: "I like it when Prince William goes dandy. He's got all the proper wardrobe when they do the hunting thing. They kill that!"

"Prince William is following in his father's footsteps as a great ambassador for British style," GQ added. However, he was eclipsed by his brother Prince Harry who was a new entry at five. Other inclusions in this year's list include Doctor Who star Matt Smith, Sir Elton John and Simon Cowell.
