Sharon shared the news on Twitter on Wednesday afternoon, writing, "As some of you may have heard, Ozzy was admitted to hospital following some complications from the flu."
She continued, "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."
According to our sources, Ozzy checked into Keck Hospital of USC on Monday. We're told Sharon and Jack showed up at the hospital with security in tow.
Shortly after arriving, our sources say Sharon left and returned a short time later with a suitcase and a blanket — a sure sign she planned to stay by Ozzy's side.
Sure enough, Sharon skipped Tuesday's episode of "The Talk."
Last week, Ozzy Osbourne announced that he was postponing the European leg of his tour with Judas Priest due to illness. He also postponed other shows due to the flu.
Ozzy released a statement after the cancellation, saying, "I'm completely devastated for having to postpone the European leg of my tour. It just seems that since October everything I touch has turned to s—. First the staph infection in my thumb and now coming down with the flu and bronchitis."
He continued, "I want to apologize to all of my fans who have been so loyal over the years, my band, my crew and to Judas Priest for letting you all down. However, I promise the tour with Judas Priest will be completed. It’s being rescheduled right now to start in September. Again, I apologize to everyone. God Bless. Love you all, Ozzy."
