Monday, January 30, 2012 - Paris Hilton arrives to a medical building in Beverly Hills, CA and gets aggravated when she is swarmed by photographers. The heiress covers her face with her handbag and says, "I'm tired," and fires back, "shut up!" when asked if she partied the night before. Later she explains, "I'm really tired. I'm just going to the dentist. My teeth hurt."
