Britney Spears has ditched her trademark blonde locks in favour of a much darker shade.

The Work B**ch singer shared her new look on her Instagram account and while we loved her blonde, the Baby One More Time hitmaker does make a pretty brunette.

She captioned the photo: “Spice up Valentine’s Day by getting ‘Naughty & Nice’ ((pun intended))”

We’re thinking the Instagram snap had more to do with promoting her new perfumes, Fantasy Britney Spears the Naughty Remix and Fantasy Britney Spears the Nice Remix, than her hair though.

This is not the first time the 32-year-old has gone brown and it seems February is her favourite month to change her hair colour; the mum-of-two was spotted sporting a new brunette “do” at Elton John’s star studded AIDs Foundation Academy Awards Viewing Party in February of last year.

We are loving the new hair, Brit – although the Toxic star can do no wrong in our eyes.
