Kim Kardashian is out to prove that just because she's turning 30 doesn't mean the fun has to end.

On Sunday's all-new episode of Kim and Kourtney Take New York, Kim celebrates her 30th birthday–in a wild way.

At her blowout bash at Tao nightclub in Las Vegas, Kim has a great time drinking, dancing and partying with friends–and tweeting about it. "One white russian coming up!" she tweeted during the night. "Hmmm who can I drunk dial tonight?

The Kardashian sisters enjoyed a special performance from ex-Destiny's Child singer Kelly Rowland, who dedicated "Bootylicious" to Kim.

But after the ladies leave the club, the partying doesn't stop. Kourtney Kardashian talks Kim into doing her first keg stand.

"I get what Kourtney's trying to do," says Kim. "She's trying to teach me that it's okay to loosen up and thirty's not the end of the world."

For more wild show moments — including an impromptu proposal and Scott Disick's nervous return to Las Vegas  — watch the clips (above).

Kourtney and Kim Take New York airs Sunday at 10 p.m. (EST) on E!
