So much for not seeing each other in Sin City!

Although Kim Kardashian swore to us that she was going to celebrate her bachelorette party separately from Kris Humphries Saturday night in Vegas, she couldn't resist surprising her man during his soiree.

But first, she kissed her single girl status goodbye with her ladies, lots of liquor and some X-rated party favors.

Kim, rocking a sash and tiara, started the celebrating at Tao with her mom Kris, sisters Khloe and Kourtney and Kris' sister Kaela all in attendance. Other female BFFs on hand for her bachelorette bash included Lala Anthony and Brittny Gastineau along with Malika and Khadijah Haqq.

Party planner Khloe made sure that things were appropriately raunchy. The ladies drank from chocolate penis straws and Kim scored a dirty cake from a midget stripper as she downed Midori cocktails.

"Omg I just saw a little person give @ KimKardashian a penis cake and do a table dance for her @ her bachelorette! It was amazing," one guest tweeted.

"My sisters are doing everything they can to embarrass me!" Kim told the crowd in the club.

Over at Lavo, Humphries got a surprise confection of his own: a cake reading Property of Kim Kardashian FOR LIFE.

His guy posse, which included Lamar Odom, Rob Kardashian, Jordan Farmar, Scott Disick and Jonathan Cheban, promptly stuck straws in the cake and teased him.

But some of the boys, including Rob Kardashian, Disick and Cheban, split off from the male bash to attend Kim's bachelorette party. They eventually brought her back to Lavo to surprise her future hubby in person.

So what was his reaction? At first, the pro NBA player seemed surprised to see his future wifey, but quickly pulled her in for a kiss in front of the crowd.

Kim didn't stay too long to chaperone, and headed out of Lavo after about 10 minutes with her girls.
