Ozzy Osbourne went out doing what he loved most.

The Prince of Darkness, who died Tuesday at age 76, was photographed publicly for the last time at his Black Sabbath farewell concert in Birmingham, England on July 5.

The rocker took the stage in front of the 42,000-person crowd at Villa Park for what turned out to be his last performance in his lifetime.

Ozzy, who was battling Parkinson’s disease, sat on stage in a black leather chair. He wore a leather overcoat and gold armband bearing his name.

The heavy metal icon performed a five-song set by himself, before he was joined by his former bandmates Tony Iommi, Bill Ward and Geezer Butler for four of the group’s songs.

“Are you ready?” Osbourne asked the audience. “Let the madness begin!”

The “Back to the Beginning” concert, which was hosted by Jason Momoa, also featured performances by Metallica, Guns N’ Roses, Slayer, Tool, Pantera, Gojira, Alice in Chains, Halestorm, Lamb of God, Anthrax, Mastodon and Rival Sons.

Ozzy and his wife Sharon, 72, also witnessed their daughter Kelly, 40, get engaged to her boyfriend Sid Wilson backstage at the farewell concert. Ozzy jokingly interjected, “F–k off, you’re not marrying my daughter,” in the middle of the proposal.

The day before his death, Ozzy shared his final Instagram post which was a touching tribute to Black Sabbath.

The post featured an image of a poster that was hanging outside of Ozzy’s dressing room door from the band’s final show. The poster showed Ozzy and his three bandmates with the words, “Back to the Beginning.”

Black Sabbath, which was formed by the foursome in Birmingham in 1968, posted a tribute to Ozzy after news of his death broke Tuesday.

“Ozzy Forever,” the group wrote alongside a photo of Ozzy during the farewell concert.

Ozzy’s beloved family confirmed his passing in a statement to The Post.

“It is with more sadness than mere words can convey that we have to report that our beloved Ozzy Osbourne has passed away this morning,” they said. “He was with his family and surrounded by love. We ask everyone to respect our family privacy at this time. Sharon, Jack, Kelly, Aimee and Louis.”

Ozzy’s daughter Jessica, 45, and his adopted son Elliot, 59, both from his marriage to first wife Thelma Riley, were left out of the family tribute.

The “Crazy Train” singer was married to Sharon for 40 years. They shared Aimee, 41, Kelly, 40, and Jack, 39. The family, aside from Aimee, starred in the MTV reality series “The Osbournes” from 2002 to 2005.

Ozzy’s health slowly deteriorated after he confirmed in 2020 that he had Parkinson’s, which left him confined to a wheelchair.

He canceled his 2023 tour three months before it was scheduled to kick off after undergoing extensive spinal surgery. He declared that his touring career was officially over, which he called “one of the hardest things” that he ever had to share with his fans.

Later that year, Ozzy said he has “at best 10 years left” to live.

Less than two weeks before his death, Ozzy announced an upcoming memoir about his life scheduled to be released Oct. 7 by Hachette Book Group.

The book’s synopsis says it includes stories about Ozzy’s time in Black Sabbath, his marriage to Sharon, his health issues and more.

“Look, if it ends tomorrow, I can’t complain. I’ve been all around the world. Seen a lot of things. I’ve done good … and I’ve done bad,” he said in a press release about the book.

“But right now,” Ozzy added, “I’m not ready to go anywhere.”
