‘Give Your Heart A Break’ songstress Demi Lovato has admitted that while she’s loving her new role on X Factor USA she’s concerned that her judging style is “too harsh”.

Speaking to XFactorUSA.com, the talented vocalist and actress explained that she’s a very honest person and doesn’t like to sugarcoat her opinions:

"My judging style is very honest, sometimes I worry that I'm too harsh? I really just say it like it is. I'm not considered the nice judge or the mean judge.

"It's really hard for me to smile if they're performing and they're horrible. I have to be super, super honest and sometimes I feel bad about it."

She recently dyed the ends of her hair baby pink and was overheard at one of the audition rounds telling a contestant, “I like your pink hair. #TWINSIES."
