Over the weekend, The Sun claimed the rocker and wife Sharon Osbourne were living separately, with a source telling the tabloid: "They are living at different addresses and not spending any time together. They row a lot.
"They aren't acting like husband and wife. It is unusual to not even have dinner together when both of them are five minutes apart."
Son Jack Osbourne later branded the reports "bulls**t" on Twitter, with Ozzy now addressing the rumours in a Facebook statement - explaining that he has been in a "very dark place" over the last few months.
The Black Sabbath star wrote: "For the last year and a half I have been drinking and taking drugs.
"I was in a very dark place and was an a*shole to the people I love most, my family. However, I am happy to say that I am now 44 days sober."
He went on: "Just to set the record straight, Sharon and I are not divorcing. I'm just trying to be a better person. I would like to apologise to Sharon, my family, my friends and my bandmates for my insane behaviour during this period... and my fans.
"God Bless, Ozzy."
