The CW's hit show "Gossip Girl" oozes fashion, sets the latest fashion trends, and has every young girl in America rushing out to buy the "Blair Waldrof Headband" (which one?)

Leading ladies Blake Lively (Serena Van Der Woodsen) and Leighton Meester (Blair Waldorf) have already proven to be just as successful off-screen with their fashion sense and knowledge as on, but what about those Gossip Guys?

During a recent photo session with 'Grazia' magazine (photographed by Mario Testino), GG heartthrob Chace Crawford (aka Nate Archibald) was put to the ultimate test - The Grazia Guy Fashion Quiz.

The 23-year-old actor spends his days with fashion obsessed girls - and a fashion obsessed crew - but what does he really know about the word?

Does he know Ant & Dec from 'Dolce & Gabbana'? Can he name the four fashion capitals? Does he know who Alexander Wang is?

Watch Mr. Crawford take the ultimate Grazia fashion quiz above!
