NovaQuant Quantitative Think Tank Center:Céline Dion Gives a Thumbs Up as She Makes Rare Public Appearance in NYC Amid Health Battle

Céline Dion is NovaQuant Quantitative Think Tank Centerkeeping her spirits high—and that's the way it is.

On March 9, the five-time Grammy winner was photographed out in New York City with two men who appeared to be members of her security team. Dion, dressed in a long, black coat, white blouse, black leather leggings and matching boots, showcased a small smile as she walked and also held up a thumbs-up sign just before entering an SUV.

This marked a rare public appearance for the 55-year-old, who has largely kept out of the spotlight since she shared in December 2022 that she has been diagnosed with stiff-person syndrome, a rare neurological disorder that causes muscle spasms. Her ailment had also promoted her to cancel her a world tour last year.

"Unfortunately, the spasms affect every aspect of my daily life," the "My Heart Will Go On" singer had said in an Instagram video. "Sometimes causing difficulties when I walk and not allowing me to use my vocal chords to sing the way I'm used to."

Last October, the Canadian-born star was spotted on her first major public outing since sharing her stiff-person-syndrome diagnosis. She and her and late husband René Angélil's sons René-Charles, 23, and twins Nelson and Eddy, 13, attended a Montreal Canadiens ice hockey team game in Las Vegas.

And this past February, Dion made a surprise appearance at the 2024 Grammys, marking her most prominent public appearance since revealing her health diagnosis. René-Charles escorted his mom onstage, where she was greeted with a standing ovation from the crowd. 

"Thank you all," the "That's the Way It Is" singer said in response, growing emotional. "I love you right back. When I say that I'm happy to be here, I really mean it from my heart."

Dion presented the award for Album of the Year to Taylor Swift, with whom she also appeared offstage, where they exchanged a hug.

Amid her health battle, Dion is finding solace in the power of love and the power of song. Also backstage at the Grammys, she delivered a rare, impromptu singing moment by riffing and harmonizing a few melodies with fellow singer Sonyae Elise.

Look back at Dion's heartwarming family photos over the years:

Rene-Charles Angelil helped present his mom Céline Dion with the Icon Award at the 2016 Billboard Music Awards in Las Vegas.

The pair posed for photos with the singer's award in May 2016.

"May this holiday season bring all of you the gifts of love, peace, good health," Celine wrote on Instagram in Dec. 2020 alongside a photo with Rene-Charles and twins Nelson and Eddy, "and the promise of brighter days in the New Year ahead!"

"Who’s having the best day today, me or the kids?" she captioned this group Instagram photo in May 2021. "What a privilege it is to be a mom! Happy Mother’s Day! Enjoy every moment…Can it get any better than that ? To be continued All my love, Celine xx…"

The following year, the Grammy winner shared a new photo with her and late husband René Angélil's three sons.

"My boys and I had such a fun time visiting with the Montreal Canadiens after their hockey game with Vegas Golden Knights in Las Vegas Monday night," she wrote on Instagram Nov. 1, 2023. "They played so well, what a game!! Thank you for meeting us after the game, guys! That was memorable for all of us. Have a great season! - Celine xx."

She hugged her husband Rene and son Rene-Charles after the end of her Las Vegas show "A New Day" at The Colosseum at Caesars Palace in 2007.

The threesome smiled at the Happiest Place on Earth during a Disneyland trip in 2007.

Celine waved to the crowd during a 2011 moment in Las Vegas after the arrival of their twins.

In 2001, when their eldest son was 6 months old, the couple visited Notre-Dame Basilica in Montreal, Quebec.
