Kim Kardashian crashes Kris Humphries' bachelor party at Lavo.

Saturday night Kim Kardashian and Kris Humphries celebrated their upcoming nuptials with separate Las Vegas bachelor and bachelorette parties at Tao at the Venetian and Lavo at the Palazzo.

The bride-to-be was joined by her mom Kris, sisters Khloe and Kourtney, friends including La La Anthony, Brittny Gastineau, Larsa Pippen, Robin Antin, Malika and Khadijah Haqq, Allison Azoff and her future sister-in-law Kaela Humphries. The women arrived in style, flying in on one of the Palazzo’s private jets. The party started with dinner in Tao’s private dining room as Kim donned a bachelorette sash and tiara for a feast of her favorite dishes. In the middle of dinner she was surprised as Mighty Mike, a little person clad in sequin pants, vest and a bow tie, hopped up on the table to entertain the room full of women. The group toasted with Midori cocktails and then made their way to the nightclub, taking over several tables on the dance floor.

In the club star struck fans clamored to get close to the group, snapping photos with their cells phones. Kim got on the mic, telling the crowd, “This is one of my last few weekends as a single girl!” DJ Vice played “Going To The Chapel” and the whole club sang along as the bride-to-be was surprised with a cake from Gimme Some Sugar. The girls danced the night away, with Khloe Kardashian Odom serving as the unofficial photographer, taking photos of her family and friends.

Meanwhile Kris Humphries was the man of honor at his bachelor party, arriving at the Venetian and starting the celebration with cocktails and beer pong at Lagasse’s Stadium. Later in the night, Kris and friends dined on the terrace of Lavo Italian restaurant overlooking the Las Vegas Strip. Joining the New Jersey Nets player were teammate Jordan Farmer, Jason Kapono of the Philadelphia 76ers and future brother-in-law Lamar Odom of the Los Angeles Lakers. Also in the group were Kim’s brother Rob Kardashian, Kourtney’s boyfriend Scott Disick and family friend Jonathan Cheban, as well as college friends from Indiana. The gentlemen enjoyed Opus One wine and Ace of Spades Champagne along with their meal of signature dishes. They wrapped up dinner with cigars before heading up to the club.

Once upstairs in the club at Lavo, DJ Skratchy gave Kris a shout out, sending the crowd into a frenzy that had the groom smiling. He was surprised with a cake with his picture and the words “Property of Kim Kardashian For Life,” which caused his friends to tease him and poke straws into the sugar confection.

As the night went on, Rob Kardashian, Scott Disick and Jonathan Cheban made their way over to Tao to meet up with the girls and ultimately brought the whole group back to Lavo as Kim stopped in to say goodnight to Kris before heading to her suite.

The happy couple loved being able to celebrate their last moments of single life in their penthouse suites on the Palazzo and Venetian properties. The neighboring locations created an ideal environment for the soon to be bride and groom.
