Paris called off work because she was Hungover!

All Paris Hilton had to do last night for her old friends at Heatherette was sashay down a runway.



When you're coming off a booze-fueled bender, however, that's a daunting proposition
The party line was that Hilton was home sick with a nasty case of "food poisoning." A source who was with her Monday night put it another way:



"She was doing tumbler shots of tequila with Brandon Davis untill 3:30 a.m. at Butter, puked, and went home really sick. She must have been totally incapacitated the next day."
