Backstage with Celine Dion at the Grammys — and what she really thought of Taylor Swift’s ‘snub’

Céline Dion made her sensational Grammys appearance to show that her illness is “not a death sentence” — and was unfazed by Taylor Swift’s alleged snub, sources told Page Six.

The superstar, 55, has been battling Stiff-Person syndrome, a rare — and incurable — neurological disorder that makes walking difficult and has prevented her from singing the way she’s “used to.”

Dion was greeted with a standing ovation at the Crypto.com Arena in Los Angeles Sunday night as she stepped onstage to hand out the final award of the night, Album of the Year.

And despite an alleged snub by the winner, Swift, one music insider said that Dion achieved what she wanted — to show everyone that she’s back.

Swift has been dragged online for not properly acknowledging Dion as she accepted the award, but an insider who knows the latter said Dion brushed it off.

“I don’t think Céline cared and they talked backstage afterwards. But Céline was just gracious and happy to be there,” the insider said. “Of course, the right thing would have been for Taylor to acknowledge her, like Adele did years ago.”

When Dion presented Adele the Grammy for Song of the Year in 2017, the two warmly embraced and Adele made an “I’m not worthy” hand motion to Dion.

Backstage on Sunday, other luminaries paid respect to Dion and flocked to her dressing room. Page Six is told she sang with Steve Wonder — “they were just riffing,” said the insider — and caught up with Oprah Winfrey.

“She wanted to show everyone that she’s doing alright,” the insider said of Dion’s surprise appearance. “She has good days and bad days … it’s a painful disease, but it’s not a death sentence.

“She’s clearly capable of doing things and she wanted to show everyone that she’s back. She looked fantastic. The hope is that she will be able to perform.”

Dion was forced to rare public appearances since then.

On Sunday night, she flew from her home in Las Vegas to Los Angeles — accompanied by a small entourage including her stylist Jay Roach — landing at 7 p.m. PST. She was escorted onstage by her son René-Charles Angélil, 23, presented the final award of the night to Swift and was on her way home by 9:30 p.m., we’re told.

Her return to the Grammys spotlight came days after the “My Heart Will Go On” singer announced the upcoming release of her new documentary, “I Am: Céline Dion,” set to stream on Amazon Prime Video.

Directed by Oscar-nominated filmmaker Irene Taylor, it will give fans an intimate look at the singer’s life following her Stiff-Person syndrome diagnosis. A premiere date has not yet been revealed.
