Keeping an eye on the family business, Kendall and Kylie Jenner stopped by Kardashian Khaos inside the Mirage Hotel & Casino in Las Vegas on Saturday (December 15).

Older sister Kendall was looking chic in a blue blazer, skinny jeans, and black heels while her younger sibling wore a white jacket, black leather pants, and black heels.

Stoked for their quick trip to Sin City, Kendall tweeted, "hangover part 3!" but quickly clarified with, "amen Liz! RT @lizkroman: No Hangover of any number 1, 2, 3 or 4 on my watch! Geez can't @KendallJenner even make a joke, calm down everyone!"

Meanwhile, Kylie tweeted a photo of her new earring with the caption, "New piercing! #Number14."
