Ozzy Osbourne has been forced to cancel a set of show dates on his current tour as he recovers from pneumonia.

The news was first revealed in a tweet posted on Tuesday morning to the 70-year-old musician’s official Twitter account, which states that performances originally planned to take place in Australia, New Zealand and Japan have been called off.

Ozzy has announced the cancelation of shows in Australia, New Zealand & Japan. “Ozzy recently developed pneumonia & has spent some time in hospital. He is through the worst part,” says @SharonOsbourne. “His doctors have advised that he stay at home to recuperate for full 6 weeks”

The former Black Sabbath vocalist was admitted to the hospital earlier this month due to “complications” he experienced while suffering from the flu.

The shows, scheduled for March, were set to take place in Sydney, Melbourne, Christchurch, Auckland and Chiba.

Announcing the cancellations, Osbourne's Twitter account quoted Osbourne’s wife, Sharon, stating: "Ozzy recently developed pneumonia & has spent some time in hospital. He is through the worst part.

"His doctors have advised that he stay at home to recuperate for a full six weeks with no travel."

Osbourne is expected to reschedule the cancelled European shows in September.
