In a recent interview with Vogue, Dion detailed how she's been dealing with physical and vocal challenges as far back as 2008. But despite various tests, nothing was found, and she kept living her life. Then the pandemic hit, and she was forced to slow down.

"After years and years of playing hide-and-seek with myself, with my friends, with my family, with my kids,"she told the magazine,"I no longer wanted to be brave. I had tried as long as I could. It was time for me to be smart." She was eventually diagnosed with stiff-person syndrome, and hasn't been able to performsince.

"It's not just about vocal exercising and doing Pilates. It's rehabilitation physically and vocally, emotionally and spiritually the whole shebang. And I want this story to be told in a classy way. I respect my fans and myself enough for them to know the full truth."

I Am Cline Dionwill air on Prime Video on June 25.
