Britney Spears goes brunette

Pop star Britney Spears has gone brunette, ditching her natural blonde locks.

The 32-year-old singer-actress revealed her darker locks when she posted a photo on Twitter to promote her Fantasy perfumes, reported E!Online.

"Spice up Valentine's Day by getting 'Naughty & Nice'," Spears tweeted on February 9, along with the picture, which showed her holding up a bottle of the perfume while smiling in a mirror.

Last February, Spears showed up at Elton John's Academy Awards Viewing Party rocking darker locks as well.
