Justin Timberlake insists he isn't cool.
The 'Runner Runner' star - who is married to Jessica Biel - would rather be "passionate" and emotionally affected by things than worry about what people think.
He told GQ's Men of the Year issue: "Listen, 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 p***ed. Be happy. Be sad."
And the 32-year-old singer-and-actor claims his unwillingness to be "cool" has led to exciting career opportunities.
He added: "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? You know?"
Justin - who was raised in Memphis, Tennessee - also admitted he is surprised to have become a patient person after growing up surrounded by "defeatist attitudes".
He said: "It's a struggling city with a defeatist attitude. I'm from this town, and I grew up with a little bit of a chip on my shoulder, so sometimes I find it funny that I've been able to acquire the patience it takes to be kind to people in our business. Because sometimes I just want to f**king kill everybody."
