The reality star has not referenced his alleged separation from Kourtney on social media, but did return to Instagram to share a post promoting a party he is hosting in Vegas this week.
His caption read: "Come party with me in Vegas this Friday."
The response he received from some fans probably wasn't what he had been hoping for...
Several fans were quick to leave comments condemning Scott's recent behaviour and urging him to return home to Kourtney and their children: Mason, five, Penelope, two, and seven-month-old Reign.
One named Gerallaras said: "Go home to Kourt and the kids omg. Doesn't the party ever stop for you? Get your s**t together. Family is the only thing that matters at the end of the day."
Others simply told Scott to go home and see Kourtney or asked him to clarify what is going on.
Kourtney is reported to have dumped Scott, her partner of nine years, after photos emerged of him getting cosy with another woman while partying in Monte Carlo last week. Kourtney had been at home in LA with their kids at the time.
Neither Kourtney nor Scott has commented but Kourtney's stepbrother Brody Jenner said yesterday: "Well, not when I saw ... honestly when I saw those pictures, I just went, 'Uh oh!' I even showed my girlfriend. I just went, 'This isn't good.'
"Scott and Kourtney are both great. You know, obviously, Scott's gone through some issues in the past. He's worked through them."
Fans of Keeping Up With The Kardashians know Scott has struggled with partying and drinking in the past. He entered rehab in Costa Rica earlier this year for one week and later said he would return in the future to continue improving himself.
