Ozzy Osbourne recently postponed the entire leg of his European tour after dealing with the flu, and now Sharon Osbourne has revealed on Twitter that the Prince of Darkness is in the hospital.

In a tweet, Sharon stated, "As some of you may have heard, Ozzy was admitted to hospital following some complications from the flu. His doctors feel this is the best way to get him on a quicker road to recovery. Thanks to everyone for their concern and love."

The Blast reported that Ozzy was admitted to Keck Hospital of USC on Monday, with both Jack Osbourne, Sharon and Ozzy's security joining him. Sharon left for a period, only to return shortly after with a suitcase and a blanket as she prepared to stay by Ozzy's side. Sharon also was absent for Tuesday's taping of The Talk, while she continued to stay with the ailing musician.

Osbourne initially postponed the first four shows of the "No More Tours 2" U.K. run before eventually deciding to call off the entire leg. The singer was diagnosed with a severe upper respiratory infection.

At present, Osbourne's next scheduled tour date is March 9 in Australia, with shows in New Zealand and Japan to follow before he returns stateside.
