With Christmas just days away, Mariah Carey is taking some much deserved downtime after wrapping her "Christmas Time" tour last week. 

"Lambs, thank you for making my #Christmastime so special. I’ve loved singing with you every night, and I can’t wait to see you all tomorrow in Brooklyn for the last show of the tour," Carey wrote in an Instagram post on Dec. 16, referring to her final show on Dec. 17. 

Though undoubtedly a success, the tour had its share of hiccups. 

On Dec. 11, shortly before Carey was set to perform in Pittsburgh, the Grammy Award-winning singer announced that she had to cancel the show at the last minute.

MARIAH CAREY, DUBBED THE ‘QUEEN OF CHRISTMAS’ BY FANS, OFFICIALLY ANNOUNCES CHRISTMASTIME IS HERE 

"Pittsburgh, I am sorry to say, I’ve come down with the flu. It breaks my heart that I unfortunately have to cancel tonight’s show. I love you all so much," she wrote on X (formerly Twitter). 

A couple of days later, the "All I Want For Christmas" crooner canceled two upcoming performances due to her illness. 

Nearly a week prior to the sudden cancelation, a brawl broke out between fans during her show in St. Louis, Missouri while she was performing "All I Want for Christmas is You." Two men were seen on video getting into a fight as a woman tries to hold one of them back. Carey appeared unfazed by the altercation and continued belting the tune, which closed out the show.

In August, Carey officially announced that she was embarking on a 20-city nationwide tour to celebrate the 30th anniversary of her album "Merry Christmas," which featured "All I Want For Christmas." The tour kicked off on Nov. 6 at Highland, California's Yaamava Theater.

With fans waiting every year for Carey's now famously belted out line, "It's time," on Dec. 1, it's hard to believe the singer nearly missed out on becoming the "Queen of Christmas."

At the peak of her stardom in the '90s, the Grammy Award-winning artist, 55, was presented with an idea: record a Christmas album. But, there was one issue. 

"I felt it was too early in my career," she recently told The New York Times. 

However, at her core, Carey knew she was always destined to make her "own little magical, merry world of Christmas."

"I focused on all the things my mother struggled to create; all I needed was a shower of glitter and a full church choir to back me up," she said of recording her fourth studio album, "Merry Christmas," which featured original songs including "All I Want for Christmas Is You."

That "little girl’s spirit and those early fantasies of family" were the inspiration behind her massive hit 30 years ago. 

Born in Huntington, New York, Carey was the youngest of three children. Her parents divorced when she was 3 years old. 

"I had some very sad Christmases as a child, but I always try to find the bright light there," she told W magazine in 2022. 

The singer first opened up about her tumultuous upbringing in her 2020 memoir, "The Meaning of Mariah Carey."

"It was an extremely dysfunctional childhood, to the point where it’s shocking that I made it out of that at all," Carey, who allegedly experienced abuse at the hands of her siblings, told W. 

Carey's father, Alfred, was a Black aeronautical engineer and her mother, Patricia, was a White opera singer. Being biracial, she always felt different. 

"There were no role models for people who were clearly mixed or, you know, light-skinned or whatever we were categorizing it as then. So, I didn’t know who to look up to when I was growing up," she said. "It was difficult."

Despite the odds, Carey was able to persevere and when the time came to turn turmoil into joy, that's just what she did. 

"Christmas makes me happy," she told W. "People think I had this princess-style life or whatever, a kind of fairy-tale existence where I just emerged, like, ‘Here I am!’ And that is not what it is.

"When you grow up with a messed-up life and then you’re able to have this transformation where you can make your life what you want it to be? That is joy for me," she added.

"That’s why I want my kids to have everything they can have. I want them to be able to understand that they can be anything they want to be."

Carey wrote the mega hit, "All I Want for Christmas Is You," in 1994. 

"I didn’t want it to feel specific to any era, so we didn’t use sounds that were happening at that time," she told W. "That way, it would feel classic and timeless." 

Since its release, "All I Want for Christmas Is You" has become one of the longest-charting singles in any genre, spending 65 weeks on Billboard’s Hot 100, according to the Times. Her album, "Merry Christmas," has sold 18 million copies.

From her children's book and an animated film based on the song to Christmas apparel and ornaments, Carey has notably earned the title of "Queen of Christmas."

In March 2021, Carey filed to trademark the term "Queen of Christmas." According to the application filed with the U.S. Trademark Office, the term would cover a large range of items like lotions, fragrances, jewelry, mugs, clothes, food, ornaments and music. 

"I could never have imagined that [the song] would become such a major part of my life," she told W. 

MARIAH CAREY SHARES HOW HER 'MESSED UP' CHILDHOOD LED HER TO FIND JOY IN CHRISTMAS

Carey, whose 21-date holiday tour started this month, could not be more grateful for the ability to spread so much joy to others with her music. 

"It’s really rewarding, and I’m just grateful and thankful for it and for all the people that come up and say, ‘I love your music,’ or, ‘I listen to your Christmas music in July’ — that started to become a thing," she said. "I’ve always wanted to do this for my life, and so now we get to do it."

And, ultimately, Carey credits the pain she went through as a child for the joy she feels today. 

"I realized, one day when I grow up, and I do what I'm dreaming of doing, which will happen, and I won't be in these sad circumstances forever, but one day I'm just going to remember what this feels like," Carey told Oprah Winfrey for the Apple TV+ series "The Oprah Conversation" in 2020. "So I don't turn into one of those people that has lost touch with the essence of who they are, but I really did in so many ways because of so many other outside components."
