Céline Dion isn't ready to return to the stage just yet.

As a result, the "My Heart Will Go On" singer, who was diagnosed with a rare neurological disorder in 2022, has officially canceled her Courage World Tour.

"I'm so sorry to disappoint all of you once again," Dion wrote in a May 26 Instagram message. "I'm working really hard to build back my strength, but touring can be very difficult even when you're 100%. It's not fair to you to keep postponing the shows, and even though it breaks my heart, it's best that we cancel everything now until I'm really ready to be back on stage again."
