In a video posted to Twitter on Wednesday, Osbourne, 70, detailed a "nasty fall" that he had earlier this year, which he says is keeping him from going on tour.

"I'm not dying," Osbourne said in the clip. "I am recovering, it's just taking a little bit longer than everyone thought it would. I'm bored stiff of being stuck on a f-----g bed all day."

The former Black Sabbath frontman says he'll have to postpone his European tour dates that had been scheduled for January and February of next year, but he's recovering enough that he's keeping his North American tour dates on the calendar. The first show of that tour is scheduled for May 27 in Atlanta.

He added: "Now will you f--k off and let me get better?"
