Justin Timberlake has a "wicked cool job".

The singer-turned-actor - who has appeared several times on 'Saturday Night Live' - loves working in comedy because he finds it easy and thinks it is a good way of getting over bitterness and rejection.

He said: "I'm not a comedian, so I'll probably get crucified for saying this, but I think with a lot of comedy the impetus behind it is; I've been rejected so many times and I'm bitter and now I'm going to talk about it.

"It's almost as if 'The Social Network' was a comedy. For me, being earnest and genuine is way easier than acting like you just don't care, like you don't want to be here, like this is a drag.

"There are just so many things in the world that are a drag. For me it's like, This is a f***ing wicked cool job!"

The 30-year-old star also recalled a time when he refused to shake a fan's hand - because they had both just been to the bathroom.

Speaking to the new issue of America's GQ magazine - in which he was named Showman of the Year alongside Jimmy Fallon - Justin said: "I was at the movies this one time, and I was going to the bathroom right before I went into the theatre and this guy, as he was walking away from the urinal, zipping up his pants as he turns, recognises me, gets all excited, and makes a beeline for me, his arm out, looking to shake my hand.

"Listen, I'm not a germaphobe, but c'mon. I literally said to him, 'There's no f***ing way you're not going to wash your hands before you try to shake my hand.' You just had that hand on your penis."
