Bad news from Ozzy camp. Legendary Black Sabbath frontman has been put to intensive care amid “grave concerns” about his health, according to reports.

The Black Sabbath singer, 70, was reportedly sent to the critical facility in a private hospital after his bronchitis worsened, amid fears he could develop pneumonia.

His wife Sharon Osbourne and their children Kelly and Jack are said to have spent shifts by his bed keeping him company as he remained there for three days.

An insider told The Sun: “Poor old Ozzy hasn’t had the best of times. He’s been really struggling with flu which turned into bronchitis. Doctors feared he could contract pneumonia which, in a person over 70, can be fatal.

“This sparked a lot of panic among those closest to him, but doctors reassured everyone he was in the best possible hands.

“Ozzy’s a fighter and is getting better day by day. The worst is over, he’s smiling again, and he can’t wait to get up on stage.”
