Mariah Carey Rocks Sleek All-Black Look While Heading to Closing Night of Her Madison Square Garden Show

The Queen of Christmas, Mariah Carey, is on the move — and looking stylish!

The "All I Want for Christmas Is You" singer, 54, filmed her closing night Christmas concert at Madison Square Garden in New York City on Sunday.

While leaving for Manhattan's famed venue, photographers snapped Carey looking stylish in a black top, sleek black pants and sparkly, silver strappy heels, along with black shades and a diamond necklace as she waved to the camera.

The sold-out Merry Christmas One and All! tour kicked off on Nov. 15, with surprise guests like Ariana Grande and Jennifer Hudson joining the pop icon on stage to perform the trio's 2020 song "Oh Santa" together earlier this month.

On Sunday, Carey dropped a mini-documentary on her YouTube channel which provided an “exclusive behind-the-scenes look at the meticulous preparations and magical moments" of the tour, per a press statement released ahead of the video. "Merry Christmas one and all," the five-time Grammy winner began the video.

"Can't believe it's the last show," Carey, in a shimmering, red strapless mini-dress said of the closing night. "Excitement! Merry Christmas, New York."

The current Victoria's Secret model also released a new music video on Dec. 8 titled "All I Want for Christmas Is You (Festive Lambs Edition),"  with several celebrities making surprise cameos in the project, including Miley Cyrus, who donned reindeer ears, Nicole Richie in a Santa hat and Mario Lopez flashing a peace sign to the camera.

The star's 12-year-old twins Moroccan and Monroe — whom she shares with ex Nick Cannon — also make an appearance. 

In a PEOPLE digital cover story about her iconic holiday status, Carey revealed that this Christmas time feels extra special. 

“I've been looking forward to this Christmas for, like, the whole year,” she shared, describing what traditions she thinks are a "slay" or "nay."

“I like popcorn garland,” Carey said of the accouterments she prefers for a tree. “Slay — especially with cranberries and popcorn.”

“[Tree skirts] can be cute,” she added. “It's all about the way they're zhuzhed. You got to zhuzh them properly.”

As for tinsel in her household? "Nay,” she said.

“I am not really a tinsel fan. But I don't want to take that away from other people because it's fun. You could throw it at people. It's fun for a moment.”

The singer-songwriter also thinks that any inflatable yard decor should be kept to a minimum. “If they have, like, a cute lamb or something like that, it's more for the pool. I would go with that,”

Finally, on the matching pajama set trend, “I do that. I love that. I think it’s cute.”
