Ariana Grande has gone from Nickelodeon starlet to complicated diva in near record time.

The 21 year old Sam and Cat star has been making some extreme demands while doing publicity for her upcoming album My Everything.

Among the over-the-top behavior Grande and her team have been insisting upon are that she is to be photographed from her left side only, she is not to be asked about the Nickelodeon show where she got her start, her love life is off-limits, and no one is to ask her about the recent death of her grandfather.

According to sources who have worked with her in the past, being around Grande is “like the President is in town.” New York Post’s Page Six has some other interesting inside information from these same sources who claim, “Everyone is kind of stressed and at the same time, they’re making fun of her because it’s much ado about nothing, really.”

Another inside source says working with the singer is “very intense” and “she kind of speaks down to everyone around her.”

She’s walked out of meet and greets because she didn’t like the way she looked and some are seeing a similar type of behavior in another troubled pop star: Justin Bieber. They share the same manager, Scooter Braun, who seems to promote this type of difficulty in his clients.

Even Giuliana Rancic of E! Network has expressed her displeasure with the outrageous demands coming from Grande and her camp, having been bullied on the red carpet by her handlers with respect to shooting the young starlet on her left. “It was like you either get on the other side or we don’t do an interview,” said Rancic. “It’s one thing if it’s Mariah. I’ll get on any side. I’ll bend down. I’ll climb a ladder. I’ll do whatever it takes. But when you’re new on the block, trying to earn your stripes … You gotta do what you gotta do. Try to earn a great reputation, try to go overboard to please people.”

But perhaps there’s no greater indicator of Grande’s diva-like behavior than a source telling the New York Daily News about an appearance the singer made at a radio station in New York. She smiled for cameras, signed autographs and made nice, but when she got into an elevator, away from her young adoring crowd, she had some choice words for her fans: “I hope they all f—king die.”

Of course, this is from an anonymous source so who knows if it’s actually true. However, as Rancic described when discussing the actions of Grande, “I feel like where there is smoke, there is fire.”
