Cameron Diaz went back to her natural blonde hair colour by accident after her hairdresser used too much bleach on her brunette hairdo. The actress ditched her trademark look last year (06) to go dark - but is back to blonde after an overzealous stylist turned her hair light again. She says, "I really loved being brunette. As soon as I finished work on my last movie, I went really dark. Then I went lighter and lighter. Recently I went in for highlights and had a couple too many drops of bleach, so I'm blonde again."
