Ariana Grande was not a "problem" at her Marie Claire photo shoot, according to the women's magazine itself.

Sources told the New York Post that the 21-year-old singer, who allegedly demands to be photographed from her left side, arrived with her mother, Joan Grande, late at the cover shoot.  She was reportedly a "monster" about her hair and treated everyone terribly.

But a spokesperson for Marie Claire denied the allegations.

"Ariana did not postpone the shoot and nothing about her arrival time was a surprise to us," the magazine said in a statement to E! News. "On set, she was professional and accommodating."

"She posed for photos with Editor-in-Chief Anne Fulendwider's kids and watched some of the World Cup with the crew," added the representative about the "Break Free" hitmaker's behavior on set.

As fans of the former Nickelodeon star know, this is not the first time the Boca Raton, Florida-born actress has faced rumors of alleged diva behavior.

Earlier this week, it was revealed that the life coach of the "Sam & Cat" alum quit his job because he could no longer deal with the singer's bad attitude.

"He just couldn't take it anymore," an insider told New York Post. "Everything people are saying about her is true."

Just days after E! presenter Giuliana Rancic claimed that Grande has diva tendencies, the rumored girlfriend of Big Sean was also accused of throwing some major shade at her own fans following a recent radio show visit in Manhattan.

"She did autographs and pics and was all smiles until she got into the elevator," a shocked industry insider told New York Daily News. "And as soon as the doors shut she said, 'I hope they all f-king die.'"

Before that alleged incident, she was also accused of having an extra-large list of diva demands for her Australian chatfest, according to News.com.au.

During the promotional visit, media were reportedly instructed to steer clear of the following topics:

(1) Relationships/Dating/Ex-boyfriends

(2) Mariah Carey

(3) Sam & Cat/Jennette McCurdy

(4) Working/collaborating with Justin Bieber

(5) Her grandfather passing away
