The "My Heart Will Go On" singer, 53, said she was "heartbroken" to have to push back the Nov. 5 opening date of her new show at The Theatre at Resorts World, a hotel on The Strip that opened in June. Dion — who canceled 21 headlining performances from Nov. 5-10 and Jan. 19 to Feb. 5 — has been experiencing "severe and persistent muscle spasms" that are preventing her from performing, according to a press release. Though she is being evaluated and treated by her medical team, the spasms have been keeping her from taking part in the show's ongoing rehearsals. "I'm heartbroken by this," Dion said in a statement. "My team and I have been working on our new show for the past eight months, and to not be able to open this November saddens me beyond words. My partners at Resorts World Las Vegas and AEG have been working around the clock to get this brand-new state-of-the-art theatre ready, and it's absolutely beautiful."

"Now, I have to focus on getting better… I want to get through this as soon as I can." John Meglen, President and Co-CEO of Concerts West/AEG Presents, said in a statement that the new show dates would be announced "whenever Céline is ready."
