It will take a lot more than alleged cocaine use by her brother-in-law to top Kourtney Kardashian from partying.

With Khloe Kardashian trying to put on a brave face in the midst of a marital meltdown, her sister jetted off to Las Vegas for Labor Day weekend...

While hosting a party inside Hyde Nightclub at the Bellagio Hotel and Casino, Kourtney donned a low-cut top and walked the red carpet alongside close family friend Malika Haqq.

Okay. They were in hands at least.
