Kourtney Kardashian knew her baby daddy wasn't exactly the most devoted — but she's been sent reeling after discovering just how bad his behavior really was right before their split.
"She feels so dirty and disgusting, knowing just how low he went, an insider exclusively reveals to RadarOnline.com. "Seeing all those hookers line up outside his place was just gross and a huge wakeup call."
As Radar reported, 32-year-old Disick has been partying with everyone from girls he met right after fleeing from rehab in Costa Rica to underage teenagers in Florida.
"Kourtney's skin is crawling at the sight of him and she can barely stomach the idea of being in the same room as him now," says the insider. "She's worried she'll claw his eyes out."
Another thing she fretted over was whether or not her messy ex gave her a parting gift — one she definitely didn't want.
In fact, says the insider, Kardashian recently made sure she didn't pick anything up from Disick. "She was so relieved that everything came back clear."
