Justin Timberlakehas slammed "d***head" critics who have previously said he should quit acting.

During an interview with GQ magazine, JT addressed comments made by Variety about his film Runner, Runner - as well as Billboard's negative review of The 20/20 Experience 2 of 2.

Branding the bad reviews as a "double whammy", the Mirrors singer told the mag: "Where did all this vitriol come from? It's mean. And I'm not cut out for it.

"The movie didn't do well at the box office, so I should quit? Hold on a second. If I was somebody else, you wouldn't have said that."

He continued: "I have the number one album this week, and I shouldn't have released it? Come on, man. You sound like a d**khead.

"It just shocked me because, like, you're trade magazines. None of your opinions count. And by the way, none of you can do it."

Timberlake also spoke about his hometown in Memphis, Tennessee in relation to his critics, saying: "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."
