Ariana Grande has diva-like demands

Ariana Grande has been accused of being diva-like in her demands

The Bang Bang singer is fast developing a reputation for being one of the most high maintenance figures in the entertainment industry, and someone who recently saw her at close quarters on the set of a TV project admits that some of her behaviour is so outrageous that it's almost laughable.

Speaking to the New York Post's Page Six column, the source said: ''It's like the president is in town. 'Everyone is kind of stressed and at the same time, they're making fun of her because it's much ado about nothing, really.''

The source added: ''She kind of speaks down to everyone around her.''

This comes shortly after it was claimed that Grande, 21, stopped a photoshoot promoting her new album My Everything because she wasn't happy with the first picture.

The Problem hitmaker ordered the shoot to be stopped, complaining that her earlier requests to photographers and media weren't met, according to Australian news site news.com.au.

It's alleged that the list of requests included ''don't use natural light'' and ''do shoot only from the left side of her face''. The media were also handed a list of questions they should not ask, including any relating to ''relationships, dating and ex-boyfriends'', and ''working or collaborating with Justin Bieber''.
