The singer debuts another new look during Wednesday night's first live "X Factor" show


So much for that promise!

After telling Kelly Ripa that she wasn’t planning to change her blonde hair, Demi Lovato debuted a new brunette ‘do on Wednesday night’s first
X Factor
live show. The singer kept her bangs, which she cut this summer, and wore her hair straight and down.

“It’s coming to fall and it’s harder to maintain a healthy skin tone, and when you’re going into winter it just sucks out the color of everyone,” Lovato told reporters after Thursday night’s X Factor. “So I tend to go dark during the holidays; it’s a nice contrast. There’s one thing about being blonde and pale, but I would rather be dark and pale.”

Lovato, a natural brunette, has tried a lot of looks in the past 12 months, from pink hair and blue tips to blonde locks and a bright-red ‘do.

“She’s a chameleon — she can do anything with her hair and makeup,” her makeup artist, Jill Powell, recently told PEOPLE. “She likes to change her look a lot — it’s fantastic. She embraces new trends.”

Lovato’s new look comes as a bit of a surprise — but one we’re definitely loving. Tell us: Do you prefer Lovato as a brunette or a blonde?
