Sexy Cameron Diaz stepped it up a notch by going dark.
The famous blonde has pulled a Britney, ditching her golden locks to become a brunette. Cameras spotted the A-lister in Los Angeles Wednesday afternoon getting into her car with the new 'do.
Maybe this is her way of bringing "SexyBack" to boyfriend Justin Timberlake (not that she really needs it).
It doesn't really matter what color hair Diaz decides to rock - she's always hot in our book.
