Mariah Carey’s Wild Lifestyle and Late-Night Parties Affecting Her Health and Performances

Mariah Carey‘s all-night partying is not only taking a toll on her stage performances but may also be negatively affecting her health, sources tell GLOBE! Fans were shocked after video of a recent concert showed Mimi’s “painfully slow” movements on stage.

One commenter snarked, “Why is she moving like she’s 105 years old?” Her stilettos were part of the problem, snitches a source: “They were too high and she could barely walk in them.” But the Emotions singer,

55, is desperate to keep up with decades-younger stars by wearing sky-high heels and skimpy outfits.

“But people are also convinced she’s not taking care of herself,” spills a spy.

Insiders say the Queen of Christmas treats every night like it’s New Year’s Eve – she sleeps all day and stays up all night. Her nocturnal boozing and fast-food binges, plus not getting enough sleep, also aren’t doing her body any favors.

“She loves to pop the bubbly for the smallest thing, which means it’s a very regular thing,” a blabbermouth dishes.

Mariah, who was just nominated to the Rock & Roll Hall of Fame, is such an extreme night owl that she doesn’t eat dinner till 2 a.m.! “She loves to send her assistant out to get late-night burgers and fries and shakes for everyone,” says a source.

As readers know, she has faced a mountain of challenges in recent years, including a string of broken romances, the deaths of her mother and sister, and a bipolar II diagnosis! Her relationship with ex-husband Nick Cannon, 44, the father of her twins, Moroccan Tragi Aliso and Monroe, 13, is still a major source of stress nine years after their divorce.

“He’s always running his mouth or having another kid,” huffs a source about the Wild ‘n Out host, who has fathered 12 kids with six different women.

Mariah’s latest boytoy, 39-year-old rapper Anderson Paak, has also been branded “bad news” by some in her circle.

“Mariah has been lavishing him with gifts and blowing a fortune,” says the squealer. Meanwhile, the spendthrift songstress has racked up “$18 million in mortgage debt on her luxe Manhattan pad! “Every night is a party and that’s just not healthy.

She’s not 25 or even 35 anymore. She’s 55 and the years of loose living are catching up,” warns c sister the insider.

“People around her pray she has the fortitude and sense to turn things around.

The feeling is it’s not too late!”
