Although she doesn't actually turn 30 until this Thursday, Kim Kardashian ushered in her new decade with two weekend birthday bashes --one in Las Vegas, and the other in New York.

And what would a Kim Kardashian milestone be without tweets about it?

Friday night at Tao nightclub in Vegas, the reality TV star (in a silver John Richmond minidress and new Louboutins given to her by her siblings) paused in the partying to keep followers in the loop, reports Us.

"The festivities have started!" she tweeted to her 5 million followers. "One white russian coming up! Hmmm who can I drunk dial tonight?"

Kelly Rowland (formerly of Destiny's Child) sang 'Bootylicious' for the curvaceous birthday girl, and later, when revelers -- including Kim's sisters Khloe and Kourtney, her brother Rob, as well as Paris Hilton, LaLa Vasquez and Brittny Gastineau -- got particularly rowdy, she posted this live-action pic of her little sis hugging (mauling?) her.

"Omg," she tweeted about the photo, "Khloe Kardashian is attacking me!!!"
