Celine Dion has cancelled her “Courage” world tour due to ongoing health woes related to a rare neurological disorder.

The iconic Canadian superstar says she’s not ready to return to the stage for European and U.K. tour dates that had been set to run from August through October, and in March and April 2024.

55-year-old Celine Dion postponed and cancelled some shows last December when she announced she had been diagnosed with “stiff person syndrome,” a condition commonly marked by severe muscle rigidity and spasms.

In a statement posted to her social media, Dion says “even though it breaks my heart, it’s best that they cancel everything now until I’m really ready to be back on stage again.”

The statement says Dion’s medical team continues to evaluate and treat her condition.

Dion closed her statement saying, quote, “I’m not giving up… and I can’t wait to see you again.”
