Kim Kardashian isn't going to enter her 30s quietly.
The reality star turns 30 this Thursday, and she started partying Friday at Tao Las Vegas (hosted by Fallout: New Vegas) with a bunch of well-known loved ones: siblings Khloe, Kourtney and Rob, plus LaLa Vasquez, Brittny Gastineau, Perez Hilton, singer Kelly Rowland, rapper Trina and many many more.
Kim -- who seldom drinks -- even indulged in some alcohol for the big occasion. "The festivities have started!" she Tweeted. "One white russian coming up! Hmmm who can I drunk dial tonight?"
For the occasion, the star wore a tight John Richmond mini-dress with silver sequins. On her feet: spiky, brand-new Louboutins, a joint gift from her siblings Khloe, Kourtney and Rob.
One major hitch about the shoes: Kim tripped, and one of the shoe spikes "literally stabbed me right there in my [ankle]," she told UsMagazine.com at the bash. "I started bleeding! It's pretty bad."
How does the big milestone feel? "I have mixed feelings," Kim told reporters. "Like, it sounds so old. And then the other half of me is like, I feel so accomplished and it's really no different than 29."
Kim added that she plans to "chill out and be calm" in her fourth decade. "I did a lot in my 20s. I did a lot in my teens. God I feel old. I'm so freaked out!"
Tweeting throughout the bash, she added: "We're fly like a G6." Former Destiny's Child singer Rowland even treated the birthday girl to a rendition of "Bootylicious."

"I love u," Kim wrote of the Tao Las Vegas group. "The crowd is crazy!"
Her younger sister Khloe, 26, got extra rowdy as the night progressed. "Omg," Kim wrote. "Khloe Kardashian is attacking me!!!" with a photo documenting the "attack."

The celebration's not over yet, either: Kim has another bash scheduled later this weekend.
