Celine Dion made a surprise video appearance at Eurovision on Tuesday, 37 years after winning the song contest for this year’s host nation, Switzerland.

The music superstar delivered a pre-recorded message to the multi-national singing competition as Dion continues to battle a rare neurological disorder called Stiff Person Syndrome.

Céline Dion made a rare appearance during the first semi-final of the Eurovision Song Contest with a brief, pre-recorded message. The star won the contest for Switzerland in 1988, and it had been rumoured she would take the stage as the ceremony returns to the country this year.
