The singer has topped GQ magazine's list of the Ten Most Stylish Men in America for his impact on fashion and his ''knack for targeting trends.''
Justin – who has his own clothing line William Rust – topped the list because of his willingness to take style risks with his use of hats, three-piece suits, skinny ties and facial hair.
The list also includes T.I. - who features on Justin's song "My Love" - Kanye West, Jason Schwartzman, hotelier Andre Balazs and photographer Alexi Lubomirski.
Despite his grand title, Justin believes British supermodel Kate Moss is the ultimate fashion icon because she "could put a barrel on and it would be some sort of statement."
Justin - who has been dating actress Jessica Biel since early 2007 – was recently thrown a surprise party by Jessica to celebrate turning 28.
A source said: "Justin was totally blown away when he walked in. He had no idea."
