Justin Bieber Comedy Central Roast jokes revealed

A series of jokes from Justin Bieber's Comedy Central Roast have been revealed.

The singer filmed his show recently as a number of celebrities and comedians poked fun at him.

The programme will air in the US on March 30, but a number of quips made during the show have been uploaded online.

Snoop Dogg said: "You have left so many horrible and unwatchable videos, you should change your name to Vanilla ISIS."

Host Kevin Hart joked: "Justin's Canadian. He's actually considered American, because no Canadian has ever been this much of an asshole."

Martha Stewart quipped: "Justin you have no idea what you're in for. I'm sure it's great to have 60 million followers on Twitter, but the only place people will be following you in jail is into the shower."

Shaquille O'Neal said: "Last year, you were ranked the fifth most-hated person of all time. Kim Jong-Un didn’t rank that low. And he uses your music to torture people.”
