Céline Dion diagnosed with "very rare neurological disorder" that prevents her from singing normally

Singer Céline Dion announced that she is rescheduling her spring 2023 shows and canceling eight of her concerts planned for next summer after being diagnosed with a "very rare neurological disorder." 

The 54-year-old French Canadian singer, known for hits "Because You Loved Me," "My Heart Will Go On" and "The Power of Love," posted two videos on Instagram on Thursday – one in English and another in French – revealing that she suffers from "stiff-person syndrome." 

"I've always been an open book and I wasn't ready to say anything before, but I'm ready now," Dion says in the video, growing visibly emotional. "I've been dealing with problems with my health for a long time and it's been really difficult for me to face these challenges and to talk about everything that I've been going through."
