Kim Kardashian and her fiance Kris Humphries had their respective bachelorette and bachelor parties over the weekend in Las Vegas.

After partying playing with penis straws, eating cakes shaped like penises and watching a midget stripper at TAO nightclub for her bachelorette party, Kim and her crew of 20, which included La La Vazquez, her sisters Khloe and Kourtney, mom Kris Jenner, her BFF Britny Gastineau and more, mozied on over next door at Lavo and crashed Kris’ bachelor party.

Kim and her friends mingled with Humphries’ guests, which included Kim’s younger brother Rob Kardashian, celebrity publicist Jonathan Cheban, Kourtney’s boyfriend/baby daddy Scott Disick and Khloe’s husband, basketball star Lamar Odom, while cameras were rolling during both parties for an upcoming episode of “Keeping up with the Kardashians” that will document Kim and Kris’ wedding and the events leading up to it.

“My sisters are doing everything they can to embarrass me,” Kim Kardashian told the crowd at her bachelorette party earlier in the evening. “Amazing night!” Kim tweeted afterward. “DJ Vice killed it! The ladies shut down Tao.”
