Justin Bieber ''might need surgery'' after bursting his eardrum.

The 20-year-old pop star may require an operation to repair the perforated tissue in his ear after he damage it by leaping off a cliff, which is known as 'tombstoning.'

Taking to his Twitter account last night, he tweeted: ''Busted my ear drum cliff diving. Doc says might need surgery now. Sucks. (sic).''

However, the 'Baby' hitmaker, who has recently rekindled his romance with on/off girlfriend Selena Gomez, believes the painful injury may delay the release of his upcoming music but he's adamant it won't cause any long-term issues with his career.

He reassured fans an hour later: ''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.''
