Former star of Grey's Anatomy, and current star of ZzzQuil ads, Katherine Heigl, is suing the popular NYC drug store chain Duane Reade after they tweeted a papparrazi photo of her leaving one of their locations while carrying two of their bags. The tweet read "Love a quick #DuaneReade run? Even @KatieHeigl can't resist shopping at #NYC's favorite drug store." Now Heigl wants them to stop the "false advertising," and cough up six million bucks.
