Bang bang! Jessie J is shooting down prevalent rumors that Ariana Grande is a huge diva. The songstress told Us Weekly at the William Rast debut at Lord & Taylor in New York City on Wednesday, Oct. 9, that Grande isn't a diva in the slightest. Instead, Grande just knows "what she wants," Jessie says.

Grande, who collaborated with Jessie J and Nicki Minaj on the track "Bang Bang," has made headlines recently, with claims that she's a disaster to work with and high-maintenance, but Jessie J, 26, tells Us it's a misunderstanding that she herself is all too familiar with.

"I always say, judge a person when you meet them," Jessie told Us when asked about the rumors. "I’ve met Ariana, and there’s a very thin line between 'diva' and 'survival.' And a lot of people can’t [differentiate that] — and I’ve had that," she said. "I've had the diva stuff. And it’s when people can’t cope with how passionate you are, and how much you care," the "Price Tag" singer explained.

"She's super talented, she's very young, and she's very sure of what she wants," Jessie J added of Grande. "I think she’s wonderful. She’s great."
