Fleetwood Mac star Stevie Nicks always smiles for the cameras these days after she was reprimanded for being too sullen by a four-year-old. The rocker was reminded of her all-too serious poses at the preview party for rock photographer NEAL PRESTON's new exhibition at the Morrison Hotel Gallery in Los Angeles last night (09NOV06), and scowled when she saw pictures of herself taken in Venice, California in 1982. She said, "I never used to smile in photos, but then I posed with this little girl and she said, `You're not making a smiley face.' It was very touching. "Ever since then, I've always made sure I smile in photos." Nicks wasn't the only famous face checking out Preston's exhibition - Neil Diamond, rocker Anthony Kiedis and LAKE + PALMER star KEITH EMERSON also showed up for a blast from the past. When Diamond came face to face with a concert photo Preston had taken of him 30 years ago, the stunned SWEET CAROLINE singer said, "I cannot remember that shot. It was taken 30 years ago."
