“[It was] not exactly one of my greatest achievements,” the Black Sabbath singer, 71, said in the “Biography: Nine Lives of Ozzy Osbourne” documentary, which premiered on A&E on Monday (via Us Weekly). “I felt the calmest I had ever felt in my life. I was just peaceful. … All I remember is waking up in [England’s] Amersham jail and I asked the cop, ‘Why am I here?’ And he says, ‘You want me to read your charge?’ So he read, ‘John Michael Osbourne, you have been arrested for attempted murder.’”

Sharon, 67, said she “didn’t recognize” her husband, who had limited recall of the events, that night because of how intoxicated he was from drugs.

“I had no idea who was sat across from me on the sofa but it wasn’t my husband. He goes to a stage where he gets that look in his eyes, the shutters were down and I just couldn’t get through to him,” the “Talk” co-host explained.

“And he just said, ‘We’ve come to a decision that you’ve got to die.’ He was calm — very calm — then suddenly he lunged across at me and just dived on me and started to choke me. He got me down on the ground on top of me.”

The talk show host said she managed to find “the panic button” and press it, prompting the cops to arrive. The rocker, who revealed his Parkinson’s disease battle earlier this year, went on to spend six months in medical detention.

“Thank God the judge put him in treatment for six months. I had time to really think about what he should do,” she said. “I told him, ‘I don’t want the money … but if you do this again, either I am going to kill you or you are going to kill me. And do you want that for the kids?’”

Ozzy and Sharon share three children: Aimee, 37, Kelly, 35, and Jack, 34.
