Celine Dion cheers on the Boston Bruins as she makes a surprise appearance with her teenage sons amid her battle with Stiff Person Syndrome

Celine Dion made a rare appearance at the hockey game between the Boston Bruins and the New York Rangers with her twin sons on Thursday.

The My Heart Will Go On singer, 55, looked on in awe as she cheered in excitement from the sports box with her twins Eddy and Nelson, 13.

But her sons didn’t seem to share her enthusiasm as they watched the Bruins get beaten 2-5 by the Rangers at TD Gardens in Boston.

Celine – who is battling Stiff Person Syndrome – looked effortlessly chic in a chic camel trench coat, which she paired with an elegant champagne silk blouse.

Keeping her look casual, the singer paired her elegant ensemble with skin-tight cream jeans and suede boots.

Her boys fully embraced their inner sportsmanship as they stepped out in matching Bruins jerseys.

But Celine – who was recently spotted on a rare outing in NYC earlier this month – attended the fight for more than just being a spectator.

The Boston Bruins brought the legendary singer into their locker room to read the starting lineup before the team’s game.

Celine grew up in Quebec, where the Montreal Canadiens reign in a different country than their rival Bruins.

Still, she stepped into the middle of Boston’s locker room and passionately read out the lineup card as if it were her own concert.

“Thank you so much for getting ready for me tonight,” she began, commanding the locker room attention of Bruins head coach Jim Montgomery.

With his sons in the dressing room behind him, the icon didn’t stumble through the players’ names.

Instead, she knew all their nicknames for the approval of the Boston list.

‘Alright! Ahead, Heino!’ Dion was singing in reference to Bruins winger Danton Heinen.

“You’re making me hungry, Pasta!” Dion yelled at Boston’s David Pastrnak.

“My name starts with a C and we’re going ‘C-Mac!’” Dion said, calling out Charlie McAvoy.

She was also featured on the jumbotron during the second period of the match, drawing a huge reaction from the crowd.

But unfortunately, Celine, who was diagnosed with Stiff Personal Syndrome in December 2022, did not end up being lucky for the Bruins as they lost at home to the Rangers.

Last week, Celine admitted she is ‘determined’ to get back on stage and perform again amid her battle with the rare disorder.

As the mother of three shared a sweet tribute to her three sons on Instagram, Celine took the opportunity to praise her friends, family and fan base for the love she receives.

In the caption, Celine wrote to her 6.4 million followers: “Today the world recognizes International SPS Awareness Day.”

‘As many of you know, in the fall of 2022 I was diagnosed with Stiff Person Syndrome (SPS),’ she continued.

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

The star then expressed: ‘I am deeply grateful for the love and support from my children, family, team and all of you!’

‘I would like to send my encouragement and support to all those around the world who have been affected by SPS. I want you to know that you can do it! We can do it! Love Celine xx…’

Stiff Person Syndrome (SPS) is a degenerative condition that causes muscles to tense and spasm uncontrollably. Ultimately, it leaves patients looking like ‘human statues’ as it gradually locks up the body, leaving people unable to walk or speak.

There is no cure for SPS, but there are steps that can be taken to curb the symptoms – something Celine revealed she is exploring.
