Rob! Kourtney! Scott! ‘Keeping Up’ Klan Hits Vegas (PHOTOS)

Rob Kardashian, Scott Disick and  Kourtney Kardashian lived it up in Sin City on Saturday night — with separate agendas.

With this jet-setting family, even when you can get a few members in the same town, they can’t all be contained to just one place!

Kourt was out with her main man, while Rob stepped out solo.

Scott played host for the evening at Chateau Nightclub and Gardens at Paris Hotel and Casino. As ever, he looked sharp in a crisp suit. The man does not know the meaning of the word casual!

Meanwhile, Rob soared over to JET at the Mirage to take in the nightlife.

Over Twitter,  the two had a rivalry going about which spot would be the hottest. Rob tweeted:

NOT! JET will be 100%! RT @ScottDisick: chateau night club in vegas will 100 percent be the best party in vegas tonight! #july4thweekend

Although we presume he was asleep in the hotel, we sure know little Mason loves to party — with his parents!
