Jessie J: 'Ariana Grande is not a diva'

British singer Jessie J is adamant fellow pop star Ariana Grande has been unfairly branded a "diva" because of untrue rumours about her bad behaviour.

The Problem hitmaker was recently accused of scrapping her entire promotional schedule in Australia because she was unhappy with pictures from a photoshoot, while a group of fans in the States called her rude for shunning them at a meet-and-greet session.

Grande has insisted the incidents have been blown out of proportion, and now her Bang Bang collaborator Jessie J has spoken out in her defence.

The Price Tag singer tells the New York Daily News, "She's wonderful and she's had an extraordinary amount of success and the media sadly can't keep celebrating that, so they have to find something that they feel people would want to be more nosily interested in. I've had the 'diva' stamp, too... and there's a very fine line between diva and survivor.... (The accusations are) complete and utter bulls**t and you can put that in (your story)!"
