You probably know her best from "Knocked Up" or "Grey's Anatomy," but this seems like a wack thing for a celeb to do. Katherine Heigl is apparently suing drug store Duane Reade (which I love btw, cuz they cell that BLK Water stuff) over some social network posts. According to her lawsuit which was filed yesterday, Katherine claims the store used her name & a paparazzi pic of her leaving the store on it's Twitter & FB pages without her permission. 

“Love a quick #DuaneReade run?” the Walgreen Co. subsidiary wrote on its account March 18 alongside the pic. “Even @KatieHeigl can’t resist shopping #NYC’s favorite drugstore.” The post, also shared via Facebook, was used to “imply falsely that Plaintiff endorses Defendant,” it was written in Heigl’s 15-page lawsuit.


Now I'm no expert on things like this, but it just seems kinda petty!
