Demi Lovato ‘Relates’ To Britney Spears On ‘X Factor’

'Factor' judge also says 'it would be an honor' to collaborate on music with Spears.

Demi Lovato is having a blast as one of the four judges on “The X Factor.” Nestled alongside Britney Spears, Simon Cowell and L.A. Reid, the onetime Disney princess has found her voice as a singing-competition referee. And she describes her judging style as tough but loving.

“Well, you know, I try to be positive as much as I can,” she explained to MTV News on Sunday, just before she jetted to Miami for the show’s boot camp. “But sometimes you’ve just got to tell people that singing is not for them. When I hear a good singer, sometimes I critique them so that they can be better. And it’s not that they’re bad.”

In fact, Lovato sometimes will go to bat for a singer despite what the other judges have to say. “But then when I hear someone that I absolutely love or someone that I believe in, I’ll stick up for them, even if everyone else votes no,” she said. “I’m really honest on the show and sometimes I come off as the toughest judge. I guess you can say I speak my mind.”

So, which of those other judges does she agree with most at the end of the day? “It’s unpredictable. Like sometimes I cannot see what Simon sees in the people he puts through. And same with Britney,” she explained. “I’m like, ‘Britney, what are you thinking?’ But there are more times I relate with Britney [better] than Simon, actually. Maybe because we’re the two girls on the show.”

While her focus on set is to judge the show, when asked if she and Britney have talked about making any music together, she said, “It would be an honor, but no plans yet.”

Lovato, who in addition to judging the show is also on her summer tour , added that she has no regrets about signing on. “Everyone’s amazing,” she said. “It’s awesome.”

On Monday, all four judges appeared at the Television Critics Association summer press tour via video conference and chatted about the next season of the show, which kicks off on September 12.

“I’m not going to lie about this,” Cowell said of Spears during the press conference, according to The Hollywood Reporter. “I always said the no. 1 person I wanted on one of these shows was Britney. She’s intriguing. You see a different side to her and she’s a really great judge. … Britney is quite mean, which you’ll soon discover.”

“I think it’s just based on myself and who I am,” Spears responded. “I’m a very honest person.”
