Days after the troubled reality star split from his girlfriend of nine years, Kourtney Kardashian, the Keeping Up With The Kardashians star returned to Instagram, where he encouraged fans to come part with him in Las Vegas.

"Come party with me this Friday in Vegas @1oaklv," Disick wrote, along with a promotional photo for the event.

Disick's rumored new woman, Chloe Bartoli, also updated her Instagram on Tuesday. However, unlike Disick, she offered no caption.

While Disick and Kardashian have been on-and-off for a while, a source recently said that this time, Kardashian was sure of the breakup.

"Kourtney has always taken Scott back and been by his side, but now with three kids it has gotten old," a source told E! News of the split. "Kourtney has to do what's best for the kids."

"They fear he is out of control and has fallen off the wagon," the source continued. "He is partying hard and they are concerned...He's clearly unraveling. He was a mess in NYC last month with the drinking and partying and he's been in a downward spiral ever since. He's been in trouble before, but this is on another level."

Keeping Up With The Kardashians airs on Sundays at 9 p.m. on the E! Network.
