Whoa mama! Newly engaged Kim Kardashian is pulling out all the stops since giving birth to baby North West and more recently accepting Kanye West's marriage proposal. The Keeping Up With the Kardashians star showed off her gorgeous post-baby body while celebrating her 33rd birthday at Tao Nightclub in Las Vegas on Friday, Oct. 25.
Dressed in a white lace curve-hugging dress, the first-time mom revealed major cleavage during her night out. She wore her honey locks down for her big blowout and stunned in a tight-fitted white bustier top.
"I'm wearing a designer that I got in Paris," Kardashian told Us Weekly of her outfit at the big bash. "I bought this when I was really, really, really pregnant. This was going to be my goal dress and the fact that I'm fitting into it on my birthday make me really happy."
Kardashian also shared her outfit via social media during the night. "Let the bday festivities begin Vega$," Kardashian wrote via Instagram. Alongside the caption, the reality star posed for a picture with close friends, including big sister Kourtney Kardashian, Glee's Naya Rivera, Pussycat Dolls singer Robin Antin and Blac Chyna. (In late September, Kardashian showed off her svelte body once again when she and West went on a double date with Chyna and Tyga at Hakkasan in L.A.)
Hours earlier, Kardashian shared a photo of her new fiance and close pals landing in Las Vegas, clearly pumped for the festivities to come. "Vegas…we've arrived!!!" she wrote via Instagram. With the caption, she posted a photo of her posse posing in front of two cars at the airport, with West, 36, standing on the hood of one.
The party just tops off the week for the blushing bride-to-be. On Oct 21, the Yeezus rapper got down on bended knee to propose to Kardashian at the AT&T Park in San Francisco, Calif., and presented her with a stunning (and massive!) diamond rock made by designer Lorraine Schwartz.
