Celine Dion has marked Christmas Eve with a playful social media post, sharing a video of herself dressed as the Grinch while parodying a well-known monologue from the festive film.

The singer uploaded the clip to Instagram on Wednesday, appearing seated by a fireplace in a full Grinch costume complete with bright green makeup. She opened the video by talk-singing the chorus of “All by Myself” before launching into a parody of the Grinch’s scheduling monologue from the 2000 Jim Carrey film “How the Grinch Stole Christmas”.

“The nerve of those Whos, inviting me down there on such short notice. Even if I wanted to go, my schedule wouldn’t allow it!” Dion said, while holding a small dog wearing antlers similar to those worn by the Grinch’s dog, Max.

She continued by listing a series of mock appointments: “4:00 — exercise my voice. 4:30 — wake my children up. 5:00 — solve world hunger. Tell no one. 5:30 — jazzercize. 6:30 — dinner with me. I can’t cancel that again! 7:00 — wrestle with my creative ideas.”

Dion went on to add her own twist to the monologue. “I’m booked!” she said. “Of course, if I bumped my creative ideas to 9:00, I’ll still have time to lay in bed and scroll TikTok videos endlessly. Or I can just simply wish everyone a merry Christmas and a happy new year… boring!”

She ended the video by returning to “All by Myself”, singing the opening line: “When I was young, I never needed anyone.”

The festive post offered fans a light-hearted moment from the singer during the holiday season.
