Back to brunette! Britney Spears revealed darker locks in a snapshot she posted on Saturday, Feb. 8, while promoting her Fantasy "Naughty Remix" and "Nice Remix" perfumes.

"Spice up Valentine's Day by getting 'Naughty & Nice' ((pun intended))," Spears, 32, wrote. In the pic, the "Work Bitch" songstress is seen smiling at a mirror and holding up her fragrance bottle. (On Feb. 4, the entertainer was still sporting her lighter locks, as seen in a photo she posted while rehearing for one of her Las Vegas shows.)

This isn't the first time the mom of two has changed up her 'do. Last February, Spears -- then off her fresh split with fiance Jason Trawick -- traded in her trademark blonde locks for a brunette hue when she attended Elton John's Oscars party. She complemented the dark tresses with a black, cleavage-baring sequined gown for the special evening.
