Justin Timberlake is cool enough to be on the cover of GQ's Men of the Year issue -- but if you ask him, he's not cool at all.

J.T. tells the men's mag that, despite two number-one albums, a sold-out stadium tour and a gig at the White House, "I’m not cool… Being cool is about keeping your blood pressure steady. So no. Don’t be cool. Be passionate. Be dedicated. Be tenacious. Be uncompromising. Be pissed. Be happy. Be sad…. I’ve made a career out of doing things that I should not be doing. I wasn’t cool about it. Because being cool would have meant I passed up on those opportunities. If you do that, it’s because you’re afraid. And what are you afraid of?"

GQ's Men of the Year issue hits newsstands on November 19th.
