"Just to set the record straight, Sharon and I are not divorcing," Osbourne wrote. "I'm just trying to be a better person."
In the same post Ozzy explains that he has spent the past year and a half "drinking and taking drugs."
"I was in a very dark place and was an asshole to the people I love most, my family," he continues. "However, I am happy to say that I am now 44 days sober."
He concludes by offering an apology to "Sharon, my family, my friends...my band mates" and "my fans" for "my insane behavior during this period."
As for Ozzy, he's getting ready to hit the road with Black Sabbath in support of the band's upcoming studio album 13 — the first to feature Osbourne, Tony Iommi, and Geezer Butler since 1978's Never Say Die!
