Mariah Carey is known for putting her whole heart and soul into Christmas every year, but this year, she is going beyond what is expected of her and causing her friends to be concerned with her excessively intense performance.

“Mariah’s always been turbo charged when it comes to Christmas, but this year she’s pushing herself to extremes. She’s rehearsing non-stop and not getting enough sleep. It’s become a real obsession. She’s always been a night owl, but lately there are many nights where she’s up until well past dawn, pacing in the studio, going over every tiny detail of her performances," an unnamed source told Life & Style Magazine.

The source also divulged that the singer of "All I Want for Christmas" is going to extremes because she is worried that someone else may steal her Christmas crown without her permission. All things considered, there is no doubt that there is a great deal at stake because Christmas is the season in which she generates the majority of her money.

The insider continued by saying that she lives in constant fear of one of her competitors coming in and cutting into her significant income because it is not just about the title; considerable money is involved. Mariah is having a more difficult time with each passing year. She is aware of the intense level of competitiveness that exists. Considering that J. Lo and Christina Aguilera are following closely behind her, it is not entirely irrational to be concerned about her.

The pressure Mariah, who is 55 years old, puts on herself is not healthy, and it is significantly impacting a number of aspects of her life. This is even though the entertainment industry is characterized by intense rivalry and competition.

Her diet has become equally as intense as her work schedule and the continual worry that she is experiencing. Right now, she is following this bizarre regimen that consists solely of liquids—juices, broths, and nothing solid. According to the source, she is confident that it will help her maintain her energy levels and make her appear even more youthful while appearing throughout the Christmas season.

One issue is that it is leaving her feeling tired. She had previously started skipping meals to engage in additional rehearsals, and now she hardly eats anything substantial. Even though she is falling apart at the seams, anyone who wants to tell her to slow down will have their head bitten off.

In August, a different source reported the same information concerning Mariah's yearly Christmas nightmare. This source asserted that the holiday season is a crucial time of the year for her financially and that she experiences this nightmare every year.

A significant portion of her income comes from holiday-themed performances and merchandise, as well as the fact that "All I Want for Christmas Is You" consistently tops the charts throughout the month of December, Fortune reported.

At the time, a source named No. 2 informed Life & Style Magazine that Mariah does not only anticipate Christmas; rather, she anticipates it with great anticipation. The magic of the holidays has become more about saving money than spreading cheer.

Mariah is preparing to start her "Christmas Time" tour, with the first show kicking off in Highland, California, on November 6, Rollingstone reported. The tour will conclude with a stop in Brooklyn on December 17.

In the lead-up to the tour, the Glitter star wowed the audience at the American Music Awards by performing the song "We Belong Together," which had already won a Grammy. Fans raved over the performance, from Mariah’s look to her whistling vocals.

“She sounds so amazing and looks amazing as well,” one person wrote via X in response to a clip of the “Hero” singer’s performance. Another person wrote, “This is what we call a timeless icon legend and music.”
