Mariah Carey dazzles in sparkly white gown as she performs during her Christmas Time tour in Atlanta

Mariah Carey took the stage in Atlanta, Georgia for her Christmas Time tour.

The 55-year-old self-proclaimed “Queen of Christmas” — who recently brought her twins Monroe and Moroccan to her concert stop in LA — looked like an ice princess as she performed her holiday hits at the State Farm Arena on Saturday night.

She modeled a shimmering white mermaid-style dress with puff sleeves and silver star accents on the glamorous outfit as she floated across the stage, matching microphone in hand.

Her signature golden locks were styled in voluminous curls, which framed her face and complemented her blush makeup.

And she teamed her look with a butterfly and diamond ring and designer bracelet as her backup dancers twirled behind her.

Nick Cannon’s ex-wife announced Mariah Carey’s Christmas Time Tour in August to celebrate the 30th anniversary of her mega-holiday hit All I Want For Christmas Is You.

The five-time Grammy winner kicked off the concert tour on November 6 in Highland, California. She will perform the final show of the tour on December 17 in Brooklyn, New York.

Her show in Atlanta was the Emotions singer’s seventh stop on the 20-show tour. After her time in the City in a Forest, she flies to Nashville, Tennessee.

The set list includes a whopping 26 songs and typically lasts about 90 minutes, during which she performs a mix of holiday classics with modern twists and her biggest hits.

Every evening she closes the show with her 1994 hit All I Want For Christmas is You, which is also called the most popular Christmas song in the world.

Last November, Carey opened up about the real history behind her famous song, which she composed with 66-year-old Brazilian songwriter Walter Afanasieff.

She told me Parade: “I started writing that on a little DX7 or Casio keyboard that was in this little room in the house I was living in at the time in Upstate New York, lifetimes ago.

‘Write down everything that was on my mind. All things that reminded me of Christmas, made me feel festive and I wanted other people to feel that.”

While it is widely known that the track took 15 minutes to write, the hitmaker revealed that the recording process was a completely different story.

“We took some time to make the record because when you listen to all those background vocals and all that stuff, you can’t do it in five minutes,” she continued. “It’s literally impossible unless you have three choirs.”

In 2014, Billboard asked Afanasieff if he knew the song would be as successful as it was when he and the blonde beauty were writing it in her New York home in the summer of ’94.

“Twenty years ago, Christmas music and artists’ Christmas albums weren’t as big a deal as they are now,” he explains. ‘Back then you didn’t have many artists with Christmas albums; It was not a known science at all at the time and there was no one making new, great Christmas carols.’

During Amazon Music’s 2019 mini-documentary, the singer revealed that her favorite line in All I Want for Christmas Is You is: “I won’t even wish for snow.”

She explained: ‘[It’s my favorite line] because I always long for snow. I always want it to be a special, festive winter wonderland.”

The hitmaker even makes annual trips to celebrity favorite Aspen Colorado to spend some time in the ‘winter wonderland’.

In November 2011, Justin Bieber released a remix of All I Want for Christmas Is You on his infamous Christmas album Under the Mistletoe.
