EVERY actress dreads the day she spots the first grey hair on her head, but Cameron Diaz, 36, has taken it in stride. The star (There’s Something About Mary), famous for her blond locks, has even decided to name her first gray hair – after her boyfriend. “She joked that she named it ‘Paul’ because he was probably the reason she had it,” a source told the National Enquirer. Diaz is dating British model Paul Sculfor.
