Nicky Hiltons 23rd Bday Blow Out

Nicky Hilton was out celebrating her 23rd birthday this past week at club Area with Paris Hilton, Brandon Davis and other pals. The group pulled up in a black SUV with the "Firecrotch" song blasted from the car stereo. The heiress was spotted sitting on a friends lap on the passenger side of the car. Is that legal in California? TMZ reported that the laughing group looked “like clowns from a clown car”.

We hear the party ended early due to a pipe burst at the club. In the meantime, Paris made sure to make a point to leave the party in a taxi cab and told the photogs "My sister has the limo!" Paris Hilton’s definition of limo is her publicist Elliot Mintz.
