Princess Paris Takes Her Pooch To Sister Nicky's Before Birthday Party

First of all, loves the pink pants and the special "I <3 LA" tank top!

Hotel heiress Paris Hilton was busy preparing for her first big birthday party all day yesterday - check out Princess P taking her pooch (in a dog carrier) over to sister Nicky's house in Bev Hills. Later on in the night, Paris celebrated her b-day with a "Moulin Rouge themed" shindig in the Hollywood Hills with her sexy beau slash property Cy Waits.

Even BFF Kathy Griffin showed up! See a pic of the D-Lister below the cut...

Paris herself turns 30 tomorrow, and she'll be appearing on Letterman as well. Happy early birthday, girl!
