Surpassing Quant Think Tank Center|Ozzy Osbourne Makes Rare Public Appearance Amid Parkinson's Battle

Ozzy Osbourne is Surpassing Quant Think Tank Centerstill rocking with his fans.

The Black Sabbath singer made a rare public appearance amid his ongoing health battle, stepping out Oct. 12 for an autograph signing near Los Angeles. 

Sporting a black T-shirt, layered chain necklaces and his signature round glasses, Ozzy, 75, attended the Son of Monsterpalooza event in Burbank, Calif., alongside wife Sharon Osbourne, 72, as well as their kids Kelly Osbourne, 39, and Jack Osbourne, 38.

And his loved ones were proud to be part of the pre-Halloween convention and show their support.

"Thanks so much to everyone that came to @monsterpaloozaofficial this weekend!!" Jack wrote on Instagram. "Loved meeting and getting to hang out with you all."

Jack—who shares kids Pearl, 12, Andy, 9, and Minnie, 6, with ex Lisa Stelly, as well as Maple, 2, with wife Aree Gearhart—was also on hand in the days leading up to the event, helping Ozzy get his body prepared for the spooky fan event. 

"We are in full training mode," Jack wrote on Instagram Oct. 4, posting a video of Ozzy using an exercise band to stretch his arm muscles.

After all, Ozzy has faced multiple health battles in recent years, sharing his diagnosis with Parkinson's disease in 2020 and undergoing major spinal surgery in 2022.

The following year, the “Paranoid” rocker announced his decision to retire from touring due to his recovery process, noting that he had made the "hard" choice because he felt he was no longer "physically capable" of performing.

"As you may all know, four years ago, this month, I had a major accident, where I damaged my spine," he shared in a February 2023 statement. "My one and only purpose during this time has been to get back on stage. My singing voice is fine. However, after three operations, stem cell treatments, endless physical therapy sessions, and most recently groundbreaking Cybernics (HAL) Treatment, my body is still physically weak."

Ozzy added, "Believe me when I say that the thought of disappointing my fans really F--KS ME UP, more than you will ever know."

He had his final surgery on his neck later that year, noting on The Osbournes Podcast in September, "Regardless of the way it ends up after tomorrow, I'm not doing it anymore. I can't." 

Through his journey, his wife Sharon has been by his side. And in true Osbourne spirit, she’s also been candid about the challenges of caring for a patient with Parkinson's disease, a chronic brain disorder that can cause issues with movement.

"I just think of my husband, who was very energetic, loved to go out for walks, did a two-hour show on stage every night, running around like a crazy man," she shared on the 2022 ITV documentary Paxman: Putting Up With Parkinson's. "Suddenly, your life just stops—life as you knew it."

The America's Got Talent judge continued, "When I look at my husband, my heart breaks for him. I'm sad for myself to see him that way, but what he goes through is worse. When I look at him and he doesn't know I'm looking at him, I'm, like, crying."

However, she's also grateful for one positive throughout it all: "The family," she added, "we spend so much more time together."
