Fame Flynet 1 / 12

It's party time! But, that may not be such a good thing.

Scott Disick is again scheduled to host a Las Vegas party this weekend, but the nightclub appearance at 1 OAK comes as the daddy of three is "spiraling out of control," according to a new report.

Kourtney Kardashian's ex has stayed private following his high-profile split from his longtime love, but People magazine reports that he's been consistently partying in his Beverly Hills, Calif., home.

"He's in a black hole," a source tells the magazine. "It's a whole lot of darkness where he's at right now. He's spiraling out of control."

Scott has been living in the bachelor pad after Kourtney kicked him out of their shared Calabasas, Calif., home. Just last week, several women were spotted leaving Scott's new digs, a home he originally bought with the intention to flip prior to the split. Scott, though, claimed he wasn't hooking up with the women and they were simply there shooting a music video.

"Scott was partying and looked a mess," a guest told the magazine of the day the women were seen -- one of them was even photographed wearing a bathrobe.

Shortly after Kourtney axed the nine-year relationship, Scott canceled a Vegas club appearance amid pressure from his friends and family, as well as the public.

Kourtney, meanwhile, has been leaning on her family to help her cope with the end of her relationship with Scott -- all of which, of course, is being filmed for "Keeping Up With The Kardashians."

"Kourtney again spent a lot of time with Khloé and Kim. The girls filmed at Hugo's in Agoura Hills," a source said of a recent filming. "She seemed happy to be with her sisters."
