While most celebs are lightening their locks this summer, Cameron Diaz doesn’t appear to be 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. Diaz must have done the dye job when she returned to Los Angeles from Miami sometime in the last 24 hours. The 41-year-old’s hair was still very much highlighted as she spent the Fourth of July holiday on the beach with new beau Benji Madden.
