While most celebs are lightening their locks this summer (or, you know, playing with colors) Cameron Diaz is not one of them. The Sex Tape actress debuted a slightly darker hair color on Thursday at the film's press event in Beverly Hills, California.

To be clear, when we say slightly, we really mean it. The star is still very much a blond bombshell; she's just rocking more of a dirty golden hue now.

Of course, the Annie actress is no stranger to visiting the dark side. In 2006 she dyed her tresses a rich brunette shade—but that lasted less than a year.
