Kim Kardashian celebrated her 30th birthday all weekend long -- with a bash in Las Vegas and New York!

First, Kim partied at TAO Las Vegas on Friday night, where she was joined by celeb friends Kelly Rowland, Trina, La La Vazquez, Brittny Gastineau and Jonathan Cheban -- plus family members Khloe, Kourtney, Kris and Rob.

The Vegas party must have been a success, since Kim tweeted after: I love all of my friends SO much! I have a feeling 30's are gonna be the best ever!

The action continued Saturday across the country in NYC, where Kim helped TAO New York celebrate its one year anniversary -- which doubled as Party #2 for Kardashian.

Missy Elliot, Adrian Grenier, Kelly Rutherford, Kings of Leon's Caleb Followill and "Real Housewives" Nene Leakes and Jill Zarin were also in attendance.
