Is Scott Disick once again ruining his chances with Kourtney Kardashian?

According to a new report, the 33-year-old has revisited his hard-partying lifestyle over the past few days in Park City, UT, during the Sundance Film Festival. The father-of-three was spotted at the Tao nightclub pop-up and allegedly threw a rager at the home he’s been renting.

“He had a pretty wild party back at his house where lots of girls were in his hot tub,” a source told the New York Post. “He has only been out at night, and stays out till 7 a.m. partying and sleeps all day.” Sounds familiar.

Scott looked upset on Jan. 15.

Given that Scott was desperate to reconcile with his love of nine years just a few months ago, his actions suggest that he’s taken a few steps back in his recovery. As fans know, the reality star completed a stint in rehab after Kourtney reportedly broke up with him over his substance abuse problems. “He has been consistently on his best behavior for the past two months,” an insider previously told Entertainment Tonight. “This is the first time we've seen Scott be this good in a very long time… That is always something Kourtney wanted for Scott — to calm down and be at home.”

Scott’s antics come just a few days after Kourt posted a cryptic message on Instagram, seemingly directed at the entrepreneur. "Tell me how to love, it's been so long," Kourtney wrote next to a selfie, quoting The Weeknd's song "Attention," which also features the lyrics, "You’re only looking for attention/The only problem is you’ll never get enough.”

Despite an apparent strain between the couple, the 37-year-old has sparked countless pregnancy rumors, most recently when she covered up her stomach in a baggy tracksuit and puffy coat.
