Céline Dion Poses with Mick Jagger and Her Sons at Rolling Stones' Las Vegas Gig: 'You Got Us Rocking!'

The Rolling Stones had a famous face in the crowd at their Las Vegas gig over the weekend.

Céline Dion was joined by her sons René-Charles, 23, and twins Nelson and Eddy, 13, as she headed to Allegiant Stadium in Sin City on Saturday, May 11 to watch the band perform.

The Canadian singer, 56, went backstage to have a photo taken with Mick Jagger, 80, during the outing, with the frontman beaming while posing next to Dion, who looked incredible in a red outfit and nude heels. 

The "My Heart Will Go On" hitmaker's three boys — whom she shares with her late husband, René Angélil — were also in the snap that Dion posted on Instagram on Wednesday, May 15.

"This past Saturday, I got a chance to catch the @therollingstones in concert on their #hackneydiamonds tour at @allegiantstadium in Vegas. What an incredible show!" Dion wrote in the caption.

"A very special thanks to @mickjagger for warmly welcoming my family. You got us rocking! - Celine xx..." she added.

The Rolling Stones kicked off their Hackney Diamonds tour on April 28 in Houston at the sold-out NRG Stadium. Over the next couple of months, they're set to perform in cities including Atlanta, Philadelphia, Chicago, Los Angeles, and Vancouver, Canada. 

Dion's post comes after she confirmed she'd been diagnosed with the rare neurological disorder, stiff-person syndrome, in December 2022.

While speaking to Vogue France in an interview published last month, Dion said of what helps her deal with the diagnosis, "Above all, the love of my family and my children, and the love of the fans too, and the support of my team."

"People who suffer from SPS may not be lucky enough or have the means to have good doctors and good treatments. I have those means, and this is a gift. What's more, I have this strength within me. I know that nothing is going to stop me," she added.

Amid Dion's diagnosis, she's only been seen at public events a handful of times. Back in February, the singer made a surprise appearance at the 2024 Grammys, taking to the stage to present the album of the year award to Taylor Swift for Midnights. 

"It was an amazing night for her. She's doing well, and the hope is that she can continue to do more and ease back in," a source told PEOPLE at the time.
