Demi Lovato Dishes: Who's The 'Jerk' Of The 'X Factor' Panel?

Singer talks to MTV News about what to expect when Kelly Rowland and Paulina Rubino join the cast.

There will be talented singers, there will be awkward auditions, but there's one thing "The X Factor" won't have season three: drama on the judging panel.

Except, of course, the friendly banter between returning judges Simon Cowell and Demi Lovato.

"No absolutely not," Lovato told MTV News at Philadelphia's Pop-Tart Crazy Good Summer Tour of whether we will see the judges argue on the show. "Other than against Simon, so that's fun."

Cowell and Lovato will be joined by Kelly Rowland and Paulina Rubio, who replaced L.A. Reid and Britney Spears and whom Lovato affectionately nicknamed her "older sisters." The four have been jet-setting across the country for auditions, and in the process have become a close-knit panel.

So, what's the key to the success of this judging panel? According to Lovato, it's all about the ladies.

"That's fun having a bunch of women on that panel, because it's like girl power and it brings a lighter energy to the show. Instead of having feuds on the panel, there's actually ... It's all positive," Lovato said. "Therefore it makes it fun to watch."

The "Heart Attack" singer, who is up for a 2013 Video Music Awards, tells viewers that they can expect Rowland to bring the humor, Rubio to bring the craziness and Cowell to "still come across as a jerk." As for Lovato? Expect her to bring the honesty.

"I've raised my bar, I put a lot of people through last year that had the overall package but didn't have the best voices," Lovato said. "And now I've raised the bar where I am not putting anyone through that I don't think has the winning vocal capability and so I say no to a lot of people. I may come across as a mean judge, but it's very matter of fact and I'm very, very brutally honest."
