While Kardashian and the kids have been at the beach, her ex Scott Disick has been in Las Vegas for several club appearances. He attended the LIQUID Pool Lounge party on Saturday, June 10, before heading to 1 OAK nightclub in the evening.
Disick, 34, caught up with Us Weekly prior to his Sin City trip and revealed that his headline-making partying in Cannes hasn’t caused any tension with Kardashian. The real estate investor was seen getting cozy with several different women while in Europe.
“I had a nice relaxing trip for my birthday,” he told Us of his Cannes adventures. “I ate dinner with all my best friends that I’ve known for a long time. That’s about it.”
