Inside Kim Kardashian’s Las Vegas Birthday Bash [PHOTOS]

Wearing a skintight white dress (NOT made of body paint), Kim Kardashian continued her 31st birthday celebrations at Marquee Nightclub in Las Vegas Saturday night (October 22nd) with hubby Kris Humphries, Khloe Kardashian, Lamar Odom, Kris Jenner and her old Dancing With The Stars partner, Mark Ballas.

Before heading into the club at The Cosmopolitan hotel, Kardashian shared a meal with friends and family at LAVO.  The group noshed on Kobe meatballs with tomato sauce, caesar salad, chickie chickie parm parm, veal and steak and toasted Kim with Midori Sour cocktails (which must go well with such a hearty meal) and champers, according to Us Weekly.

The crew partied in the VIP section of Marquee, where Khloe grabbed the mic to wish her sister a happy birthday (with a few vulgarities thrown in, for good measure).  Before heading into the venue, Kris Jenner told Us that she gets very emotional on her kids’ birthdays.  “I can’t believe [Kim is turning 31]! I feel like she’s still my 5-year-old little girl with pigtails,” the matriarch gushed.  Hold it together, Kris!

Before the par-tay in Vegas, Kardashian and Humphries gathered with friends Pink and La La Anthony at The Darby in New York City Friday night (October 21st).
