Ozzy is a featured vocalist on Malone's song "Take What You Want," which peaked at No. 8 on the Billboard Hot 100 last year. The collaboration introduced Ozzy to producer Andrew Watt, with whom Ozzy wrote his upcoming solo album, Ordinary Man. In November, Ozzy joined Malone and Travis Scott to perform "Take What You Want" at the American Music Awards — Ozzy's first live performance in nearly a year.
In addition to rehabilitating from neck surgery, Ozzy revealed last week that he is also suffering from Parkinson's disease, a diagnosis he received last February.
"Working with him and hanging out with him and being around him, you can't tell," Malone said. "You can tell he has a little difficult getting around, but he's so strong ... [Ozzy is] going to keep kicking ass."
Ozzy's 'No More Tours 2' farewell tour was postponed for the entirety of 2019. It's scheduled to resume in May. Despite the Prince of Darkness's brutal year, Ozzy and Sharon Osbourne have kept a brave face
But speaking to a CBS reporter this week on the Grammys red carpet, Ozzy expressed for the first time a shred of doubt that he'll ever be healthy enough to complete his tour.
"If I'm well enough, I'll work towards it," he said of the tour. "I'm having physical therapy every day, five days a week. I'm trying, doing the best I can. Neck surgery's not easy."
His daughter Kelly Osbourne added that her dad is making "incredible" progress.
But there's also the reality of Ozzy's Parkinson's and the effect his symptoms will have on his craft as a singer.
Experts recently noted to Forbes that 89 percent of Parkinson's patients experience speech or voice disorders because of how the progressive nervous system disorder affects the vocal cords and the throat.
