Kim Kardashian and Kris Humphries are getting married next month -- which means their wild bachelor and bachelorette parties will be going down any day now ... and we know where!

The bride and groom-to-be will celebrate their parties the same weekend in Las Vegas at two separate nightclubs, Tao and Lavo. No word yet on who gets which venue.

Kim's family members, including mom Kris Jenner, brother Rob, sisters Khloe and Kourtney and Kourtney's babydaddy Scott Disick, will all be in attendance. Kris' basketball friends are expected to attend his bash.

Kim has a long history with both Tao and Lavo, found at The Venetian and Palazzo, respectively, and has celebrated events at each location over the past five years -- including her 29th and 30th birthdays, a New Year's Eve party and even a bash with ex-boyfriend Reggie Bush.
