Celine Dion joyfully plays air guitar during surprise appearance at Bruins game amid stiff person syndrome battle

The “My Heart Will Go On” singer made her first public appearance in four years in November 2023 when she showed up at the Montreal Canadiens’ game in Las Vegas with her twins and firstborn son, 23-year-old René-Charles Angélil.

Although Dion’s sister Claudette Dion claimed the famed songstress had “lost control of her muscles,” Celine made an unexpected appearance onstage at the 2024 Grammys in February and brought tears to the crowd’s eyes.

Backstage, the “I’m Alive” performer happily sang alongside Grammy-nominated songwriter Sonyaé during an impromptu showcase of their stunning vocals.

Despite the health setbacks she has experienced since her 2022 diagnosis, Celine told fans that she is “determined” to perform again.

“Trying to overcome this autoimmune disorder has been one of the hardest experiences of my life, but I remain determined to one day get back onto the stage and to live as normal of a life as possible,” she wrote on Instagram in March.

“I am deeply grateful for the love and support from my kids, family, team and all of you!” she added alongside a photo with her sons.
