Justin Bieber is going "back to work"

He wrote on picture sharing site Instagram: "I've been on this break for too long. #newmusic #back2work #vacationtimesup #longoverdue."

The 20-year-old singer first hinted that he would be returning to the recording studio earlier this week when he perforated tissue in his ear after leaping off a cliff.

Justin broke the news of his painful injury to his 55.1 million followers on Twitter but quickly reassured fans it wouldn't have any long-term effects on his career.

He said: "Busted my ear drum cliff diving. Doc says might need surgery now. Sucks. (sic).

"My ear drum might back us up a little but I'm still bringing you this new music. Much love. Damn u cliff diving! (sic)."

Meanwhile, it appears the singer is keen to turn over a new leaf following a number of run ins with the law over the past year, and has even given up alcohol and ditched junk food in the hope of boosting his career.

A source said previously: "Justin has been boasting to his friends about his new healthy lifestyle.

"He no longer drinks and has stopped eating junk food, too. He's had a difficult few months and is hoping that this will give him a fresh start."
