The preview features Bieber mouthing along to The Prince of Darkness’s hit ‘Crazy Train’ in an attempt to be crowned the latest lip sync champion.

The series is based on the popular segment that previously featured on US chat show Late Night Starring Jimmy Fallon. Hosted by LL Cool J, the first season has already welcomed a number of A list stars, including Anne Hathaway and The Rock.

Bieber has been on a charm offensive recently, which has included an apology for his wild antics after a host of stars lined up to mock him during an appearance on US show Comedy Central Roast.

“I’ve turned a lot of people off in the last few years,” he said. “But I know I can still put out good music and turn everything all around. There was really no preparing me for this life. I was thrown into this at 12 years old.”

Bieber added: “There were moments I am proud of. And there are moments I am disappointed with myself for. But the things I have done don’t define who I am.

“I am a kind-hearted person who loves people. And through it all, I have lost some of my best qualities. For that, I’m sorry. I am looking forward to being someone you can all be proud of.”
