Paris Hilton has certain standards for celebrating her birthday. "It's not a birthday unless I celebrate it in at least two time zones," she explained on 'The World According to Paris' (Wed., 10PM ET on Oxygen).
We're sure most Americans feel that way, which is why most Americans will have to simply stop celebrating their birthdays.
But Hilton has no problems having a lavish party in New York in anticipation of the "big party in LA" in a couple days time. Until then, she had to settle for the likes of Adrian Grenier, Lil' Wayne and Kathy Griffin to keep her satisfied.
