It was a near catfight on the red carpet last night as Paris Hilton arrived at a Hollywood party minutes behind arch-enemy Nicole Richie.
Richie, who arrived with Brody Jenner, made her way down the red carpet of the Teen Vogue Young Hollywood Party as "Simple Life" co-star/ex-best friend Paris Hilton pulled up in her Escalade.
Nicky Hilton spotted Nicole still working the carpet and warned her oblivious sister. The two then fled back to their car and waited for Richie to get inside before starting a flashbulb frenzy of their own.
Adding insult to injury -- the party doubled as a birthday celebration for Nicole Richie, who turns 25 today.
