Céline Dion stepped out to enjoy a concert from another legendary performer — and it was a family affair!

The singer, 57, made a rare appearance at Paul McCartney’s Las Vegas concert on Saturday, Oct. 4. Dion was spotted in the crowd of the Allegiant Stadium show, part of his ongoing Got Back Tour, with her three sons, according to the outlet.

The “My Heart Will Go On” musician, who wore a black turtleneck and hat, could be seen clapping and raising her fists in the air as she enjoyed McCartney’s performance alongside son René-Charles, 24, and 14-year-old twins Nelson and Eddy. Dion had welcomed her sons with her husband, René Angélil, who died in 2016 from throat cancer.

The mom of three has made very few public appearances since her stiff-person syndrome diagnosis — she was diagnosed with the rare autoimmune and neurological disorder in August 2022 — but has previously stepped out to enjoy live music.

In June, Dion was once again spotted in the crowd at Allegiant Stadium, where she not only attended Coldplay’s Music of the Spheres World Tour, but also chatted with frontman Chris Martin — who serenaded her during the show.

“Well, Celine, my beautiful sister. You make my heart go on and on, near far, you’re a total superstar. Let’s hear it for the legendary Céline Dion, we love you,” the “Fix You” hitmaker said of Dion after she appeared on-screen at the show, per a fan video shared on X.

Martin’s tribute, coupled with the crowd’s applause, left “The Power of Love” singer visibly emotional.

Dion — who appeared to attend the Coldplay show with her sons — later called the Las Vegas concert “unforgettable” on Instagram, writing, My heart is still singing! 🎶.”

“A heartfelt thanks to the band and their amazing team for welcoming my family with warmth and kindness,” wrote Dion. “It was all…fantastique❤️.”

The first family appearance at Allegiant Stadium came shortly after Dion revealed how she finds strength in her sons amid her health battle — which comes with symptoms like excruciating muscle spasms, difficulty walking and breathing — for a PEOPLE cover story.

“I barely could walk at one point, and I was missing very much living,” she told PEOPLE at the time. “My kids started to notice. I was like, ‘OK, they already lost a parent. I don’t want them to be scared.’ “

“I let them know, ‘You lost your dad, [but] mom has a condition and it’s different. I’m not going to die,” added Dion. “It’s something that I’m going to learn to live with.”
