After a surprise appearance at the 66th Grammy Awards in February, Celine Dion made a rare public appearance at a hockey game in Las Vegas. He watched the Edmonton Oilers game and spent time with the players in the locker room.

The team’s official account shared on Instagram a video showing the star in an off-white cashmere knit dress, mimicking the players and making them laugh.

“It’s fascinating to me, these huge guys in flat shoes. I can’t imagine on stakes with all the equipment…” he said as he replicated a squat with a hockey stick.

Oilers left wing Zach Hyman was seen laughing as he stood next to her in the clip.

“Celine made Hyman laugh,” the Canadian team captioned the post.

The outing is one of the singer’s rare public appearances amid her battle with Stiff Person disease, reports the Daily Mail.
