Naturally a brunette, Demi Lovato is learning that blondes have more fun. 

The Heart Attack singer has received mostly positive feedback in regards to her color change, she told People in July. But, even if critics aren't a fan of her lighter locks, the X Factor judge is not bothered by their opinion.

"I don't really care if people like it or not," she told the magazine. "I like being blonde and it's fun for the summertime."

The 20-year-old also told the magazine that her spontaneous hair color change won't be her last.

"I never know what I'm going to do next," she said. "Maybe like a honey brown or a dirty blonde or something, so it's not too blonde."

Because of the constant changes, Lovato is conscious about keeping her hair healthy.

"What I do is just take care of it a lot," she said. "I do olive oil treatments, which are really easy. Also, because of my [Hispanic ethnicity], my hair is really strong naturally."

The singer, who debuted her lighter hair in May, is getting ready for season 3 of X Factor and the short trailer for the upcoming season was released in July.

The clip shows Simon Cowell introducing, Kelly Rowland and Paulina Rubiio, the two new female judges. While Cowell regards Rowland as a "total professional," the former Destiny's Child member is heard telling a male contestant, "how you doing there cowboy?"

Addressing the other female judge, Cowell said, "I think everyone is going to understand Paulina."

However, what comes out of Rubio's mouth following his remark is quite difficult to understand.

The small rivalry between returning judge Lovato and Cowell is also demonstrated. The Warrior singer teases the 53-year-old about his age, as she's often done before. But, Cowell admits that Lovato has a different attitude this year.

"She respects me," he said.

X Factor's season 3 premieres in the fall.
