Listen to Britney Spears on iHeartRadio

Oops, Britney Spears did it again.

She dyed her trademarked blonde hair to a dark color.

On Saturday, the pop princess posted a picture of herself in front of a mirror with her darker hair — holding a bottle — along with the message, “Spice up Valentine’s Day by getting ‘Naughty & Nice’ ((pun intended)).”

Spears, who has changed her hair color before, was referring to her two new fragrances “Naughty Remix” and “Nice Remix.”
