Scott Disick has already moved on from the Kourtney Kardashian split as he was snapped partying all night with a mystery blonde from Wednesday to Thursday morning in New York City.

"Disick and the mystery chick started their party adventure at his hotel ... they were spotted walking out of the Trump Soho Wednesday afternoon. They hit up a bar in the East Village ...then a house party, and eventually 1 OAK Nightclub," TMZ reported.

And the two continued their party at the Soho House before leaving the establishment at 6 a.m. the next day.

"Unclear who the young lady is, but she's the polar opposite of Kourtney Kardashian -- tall, blonde ... and obviously no issues with Scott's party lifestyle," it said.

It has been previously reported that Scott Disick's partying lifestyle and irresponsibility were the reasons for his split with Kourtney Kardashian, with whom he has three children.

"Scott tried to keep a low profile in a Los Angeles Dodgers baseball cap, along with a black shirt and jeans, but he was still easily recognisable," said Daily Mail. "His female companion meanwhile wore a short beige dress with blue ankle boots and a long cream cardigan."

Not that Kourtney Kardashian will mind Scott Disick partying with a mystery blonde.

Us Weekly reported that the "KUWTK" star is only civil towards Scott Disick for the sake of their three kids, Mason, 5, Penelope, 3, and Reign, 9 months, after the split.

"They're amicable for their kids but Kourtney is officially done," the report said. "It's hard for her, but she's moving in the right direction,"

Meanwhile, Scott Disick pointed out that his life is spiraling out of control after the split.

"Scott misses his family, but it's not enough to motivate him to change," the source claimed. "He doesn't have the constitution to cure himself of his issues."

Khloe Kardashian's ex, who was reportedly booted out of the "KUWTK" following the split, spent time in rehab for his alcohol addiction.
