Ariana Grande Honeymoon Over? Pop-Tart Allegedly Says Of Fans: ‘I Hope They All F–king Die!’

Ariana Grande is facing her latest and most serious allegation of diva behavior.

It’s alleged the pint-sized songstress with a big voice dissed fans she met while visiting a Manhattan radio station during the summer for a guest interview on a show.

According to the New York Daily News Confidenti@l team, the 21-year-old star allegedly slammed fans once they were out of earshot.

“She [Ariana] did autographs and pics and was all smiles until she got into the elevator,” an apparently stunned music industry insider told The News.

“And as soon as the doors shut she said, ‘I hope they all f—king die!'”

You didn’t misread that, it is actually claimed that Grande said of fans: “I hope they all f-king die!”

If true, this is a PR nightmare for the petite songstress, her record company and manager Scooter Braun — who already has a full plate managing wild superstar Justin Bieber.

Alleged revelations about Ariana acting as if the world owes her homage because she has more octaves than most, have been building on a day to day basis and have now reached a point where they need to be addressed as false or true by her management.

Ariana first allegedly made waves when UK tabloid The Daily Star claimed sources said she acted like “a total nightmare” during last Friday’s Stand Up To Cancer benefit.

Joel Gallen, Stand Up To Cancer’s executive producer and director, denied the claims to E! News, saying:

“The U.K. Daily Star’s story on Ariana Grande is completely false.”

However, more alleged atrocious behavior emerged after the pint-sized singer took her “Honeymoon tour” down under.

Grande was accused of pulling out of a day of meet-and-greets because she did not like how she was being photographed in a photo shoot. It was alleged Ariana’s handlers told photographers beforehand, “Don’t use natural light” and “Do shoot only from the left side of her face.”

In addition, it’s claimed the singer’s camp instructed Australian journalists they were not allowed to question Grande about her dating life, compare her to Mariah Carey, ask about rumors or her collaboration with Bieber, her now canceled Nickelodeon show and former co-star Jennette McCurdy or her late grandfather.

It was even claimed the “My Everything” star’s security attempted to strong-arm a photog into deleting pictures Grande didn’t like.

Braun took to Twitter last week in defense of his starlet, at one point ranting,

“Some people make up rumors for a living… so saying things about Ari comes with her now being a big star. But saying she isn’t a good person that ain’t gonna fly.”

Ariana, herself, denied the claims while she was in Australia on a radio show “Mike E & Emma” last Tuesday, telling her hosts “it does suck” to hear “totally untrue and annoying” rumors.

However, the next allegation is proving a tougher “Problem” to shrug off.

E!’s Giuliana Rancic publicly claimed last week that Grande elbowed her out of the way in an interview area at last year’s AMAs, to ensure the camera got her “good [left] side.”

Rancic, said of the alleged incident, “I just felt like it’s one thing if it’s Mariah. Whatever it takes to get Mariah to do an interview.”

“But when you’re new on the block, when you’re trying to earn your stripes, you’re young, you just gotta do what you gotta do.”

And the diva rumors are still piling up.

It’s claimed Grande’s team offered a $495 photo op for fans at meet-and-greets during her tour, but allegedly insisted shoots must be in groups of four to six people, not individuals.

Confidenti@l cites one purported industry insider, who said of this claim, “Really? Bieber, Miley, Britney, Katy Perry all did individual pics when they sold these packages.”

To be fair, it’s no secret that the Confidenti@l team historically dislikes Braun and that last claim really doesn’t seem so bad.

But, would Confidenti@l actually go so far as to manufacture an allegation against Grande to hurt Braun?

Either way, the claim that Grande hoped fans would “die” will need to be formally denied or explained by her rep, and sooner rather than later — as this story isn’t going away.
