Celine Dion attended Coldplay's show at Allegiant Stadium in Las Vegas on Saturday, June 6, and it was an evening she won't soon forget. The "My Heart Will Go On" singer was spotted in the crowd, and even got a special serenade from Coldplay frontman Chris Martin.

Dion, 57, shared several snaps from the concert on her Instagram, including a photo of herself in conversation with Martin, as well as a shot of her waving at the crowd and making a heart gesture with her hands after appearing on the concert's big circular screen.

"What an unforgettable evening with @Coldplay at @AllegiantStadium...My heart is still singing! 🙏," Dion captioned the post. "A heartfelt thanks to the band and their amazing team for welcoming my family with warmth and kindness."

One of the highlights of the evening was when Martin serenaded Dion once she was displayed on the big screen. "Well, Celine, my beautiful sister," Martin sang while strumming a guitar. "You make my heart go on and on, near far, you're a total superstar. Let's hear it for the legendary Celine Dion, he said, prompting the crowd to applaud.

The emotional moment left Dion visibly emotional, but she later returned to high spirits, even showcasing her dance moves.

Dion was joined at the show by her three sons - Rene-Charles, 24, and twins Nelson and Eddy, 14 - whom she shared with her late husband, Rene Angelil.

Earlier this month, Dion spoke to PEOPLE about how her children have inspired her to fight stiff-person syndrome, a rare autoimmune and neurological disorder she was diagnosed with in August 2022.

"I barely could walk at one point, and I was missing very much living. My kids started to notice. I was like, 'OK, they already lost a parent. I don't want them to be scared,'" Dion exclusively told PEOPLE. "I let them know, 'You lost your dad, [but] mom has a condition and it's different. I'm not going to die. It's something that I'm going to learn to live with."
