Big Sean's girlfriend Ariana Grande recently gained negative publicity when she stormed out of a photo shoot when the staff members allegedly failed to fulfill her demands. Grande is currently in Australia for the promotion of her "My Everything" album.

AAP  reports that the 21-year-old initially walked out of the shoot because she did not like her appearance on the camera. Grande reportedly reappeared with a noticeably cheerful mood. However, her demands when it comes to camera shots never went away.

The former girlfriend of Jai Brooks allegedly checks each shot to ensure that she looks good on them. Those that do not meet her standards were asked to be deleted right away. During the photo shoot, one of Grande's representatives allegedly demanded one photographer to delete all of the photos. After refusing, he was approached by one of Grande's security team.

It was likewise reported that several topics shouldn't be asked to the "Sam & Cat" star. These topics include her love life, her defunct Nickelodeon show or her co-star in it, Jennette McCurdy, her grandfather's death, and Mariah Carey.

"Ariana was mad that Mariah dissed her in an interview and it makes her furious to even hear Mariah's name," one of Star magazine's insider claims.

Recently, Daily Star also reported that the "Break Free" hit maker was a "total nightmare" when she performed at the "Stand Up to Cancer" telecast. Apart from being "consistently late," the brunette beauty purportedly yelled at crew members.

These claims were later denied by the show's executive producer and insisted that Grande was "very gracious" and "professional."

Big Sean's girlfriend Ariana Grande was also accused of acting like a diva by a father whose daughters were disappointed upon meeting their idol. Through a blog post, the father detailed how Grande didn't even bother talking or smiling to her fans who won MTV's meet-and-greet contest.

The "Put Your Heart Up" singer later defended herself by saying that she got too emotional: "A fan gave me a photo of me & my grandpa. I walked away because I didn't want them to see me start to cry."
