LaLa Anthony made her way to Vegas to party it up with her "bestie" Kim Kardashian for her bachelorette party.  Kim & Kris Humphries had joint bachelor/bachelorette parties at both TAO & Lavo.  WHy?  Cheaper to shoot them at the same time for their reality show.  Of course.

Pics of the fun night inside...

Kim may have said a few days ago she thought bachelorette parties are "cheesy," but her sisters Khloe & Kourtney (she's only having all her sisters as bridesmaids by the way) planned a naughty sin city night for the bride-to-be:

And the penis straw WOULD be a brown one.  Malika Haqq & LaLa sipped their drinks from a naughty party favor.

Some seemed to like it more than others.

LaLa snapped a pic of herself before leaving out.

She rocked a cute blue dress and kicked it with Kourtney & Britny Gastineau.

Twins and Kim & Khloe's god friends Malika & Khadija Haqq were there of course.

They all partied hard with the drinks of course.  Don't get any idas back there Rob.  Larsa Pippen (not pictured) was there as well.

The girls had dinner beforehand and Kim snapped a pic with her future sister-in-law Kael Humphries.

And then Kris H. came over to say hi while his bachelor party was going on over at LAVO:

Of course his fellow NBA colleague Lamar Odom was on hand.

The fellas had dinner beforehand.

Scott and Rob were there to party of course.

I'm sure fun times were had by all.
