Scott Disick's Drinking Raises Eyebrows Before Kris Jenner's Birthday Party: Watch KUWTK Clip!

Not all drama stays in Vegas. In a new clip from the next episode of Keeping Up With the Kardashians, Scott Disick's bad behavior from a recent trip to Las Vegas is on full display. 

Kourtney Kardashian's longtime partner trekked to Nevada this past November with his quasi-mother-in-law Kris Jenner in honor of the matriarch's 59th birthday. Disick, 31, scheduled a celebratory club appearance for Jenner to celebrate her big day in Sin City, but the temptation proved to be too much for the father of three, who has famously struggled with his drinking.

The episode preview opens with Jenner in a good mood, looking forward to her night ahead with loved ones including boyfriend Corey Gamble and longtime pal Faye Resnick

"I love the energy in Vegas and I love the way it feels to be here," Jenner tells the camera. "It's exciting! I'm really looking forward to dinner tonight and then going to the club."

Stepping out in a sparkling, figure-hugging minidress, Jenner jokes, "Not bad for having a birthday party at the age of 140!"

As Kim Kardashian's mom preps for her festive night, she is asked by KUWTK star Malika Haqq about Disick's whereabouts. "I don't know," she responds. "They were seen in another hotel and he doesn't know I know."

"Scott's the one who set this appearance up," Jenner adds to the camera. "I still haven't even seen him and I'm getting a little bit nervous because I'm starting to get texts from people telling me that Scott's out and about, already drinking, and we haven't even gotten started yet!"

Watch the teaser above and catch Keeping Up With the Kardashians on Sundays at 9 p.m. EST on E!.
