But that doesn’t mean it was an easy watch.

“It was so hard to watch seeing her in pain like that.

It also reminded me of Hayley’s seizure on the side of the stage a few months ago.

I could barely re-watch.”

Sheofficially returned to the stagewith her husband in April.

Hough concluded, “Celine is an absolute legend, with a unique and one in a billion voice.

We’re so blessed to witness her talent in our lifetime.

I pray she heals and returns to the stage she loves so much.”
