Which is nice.

Ariana Grande has been at the centre of some pretty serious "diva" rumours lately.

The allegations range from fall-outs with co-stars, ignoring and/or being rude to fans, being controlling on set and issuing photographers with long lists of demands. Celebrities including The Cab singer Alexander DeLeon and E! News host Giuliana Rancic have also branded her rude.

However, the latest development in this tale is pretty damning, with Ariana apparently saying she hopes her fans would "fucking die".

The singer was said to have made the comment during a visit to a radio station earlier in the summer, with more than one source overhearing her.

An industry insider told the New York Daily News: "She did autographs and pics and was all smiles until she got to the elevator. And as soon as the doors shut, she said: "I hope they all fucking die."

Ariana's representatives have so far declined to comment.
