It's brunette Britney, b---!

Britney Spears has once again changed up her hair. The iconic singer debuted a chocolate-colored hue last night, Feb. 7, during a performance of her 'Piece of Me' show in Las Vegas. 

Spears, who has rocked the blonde, brown, bald and everything in between, kept her platinum blonde hue for a while before showing off her newly dark locks during her Vegas residency last night. For the most part, fans can't get enough of the change, taking to social media with the hashtag #Brunetteney and raving about the singer's new look.

Celebrity hair stylist Brittany Lynne Hunter even took to Instagram to announce that she was the colorist responsible for the singer's new 'do, posting a snap of the pop icon's hair. Check out the picture -- and a video of Britney's performance -- below!
