Céline Dion cancels international tour due to neurological ailment.

The Canadian singer has canceled the European leg of her Courage World Tour while she battles Stiff Person Syndrome.

Céline Dion has canceled all of her tour dates for 2023 and 2024 as she continues to suffer from Stiff Person Syndrome, a rare neurological illness.

"I'm really sorry to disappoint you all again. "I'm working really hard to regain my strength, but even when you're 100%, touring can be very difficult," the 55-year-old Canadian singer said in a statement posted on her website.

"It's not fair to you to keep postponing the shows, and as much as it pains me, it's best that we cancel everything now until I'm truly ready to return to the stage." I want you to know that I'm not giving up... and I'm looking forward to seeing you again!"

Dion revealed her prognosis to fans in a heartbreaking video last December, when she postponed the European leg of her Courage World Tour until August 2023. The trip was scheduled to begin in Amsterdam and conclude in London in April 2024. 

The disorder, which affects between one and two million individuals globally, causes muscle spasms and severe stiffness that increases with time.

"Unfortunately, the spasms affect every aspect of my daily life, sometimes causing difficulties when I walk and not allowing me to use my vocal cords to sing the way I'm used to," Dion said in announcing the diagnosis, which came after months of deteriorating health.

"I have a wonderful team of doctors working with me to help me get better, as well as my precious children who are encouraging me and giving me hope." I'm working hard with my support medicine therapist every day to regain my strength and capacity to perform, but it's been a battle."
