Queen of Power Ballads Celine Dion made a heartbreaking announcement regarding the cancellation of her concert "Courage World Tour" because of her health condition.

In an Instagram post, she shared the news with everyone stating, "It is with tremendous disappointment that we have to announce today the cancellation of the Courage World Tour."

"I'm so sorry to disappoint all of you once again. 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. I want you all to know, I'm not giving up… and I can't wait to see you again!", she added.

The international singer has been recently diagnosed with a rare disease called Stiff Person Syndrome that can affect one in every million people.

This condition brought problems to Dion specifically with her mobility issues. 

SPS is a chronic condition that causes muscle stiffness and painful muscle spasms. 

How severe it may be depends from one person to another.
