Scott's partying had been an issue for many years, but after a month-long absence from the family home, during which Scott was photographed partying with his ex-girlfriend, Kourt finally decided enough was enough.
"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 shortly after the split. "Kourtney has to do what's best for the kids."
And we have to say, Kourt seems REALLY happy lately. In fact, she's kind of slaying the single life, tbh.
As for Scott, a new Us Weekly report claims that he has already moved on, at least temporarily. The report claims that Scott was hooking up with one of Kourtney's friends, fellow E! star Kimberly Stewart.
"It was going on for several weeks," a source told the mag, saying that it started after Kourtney broke up with him. "He thought they were just messing around. Kimberly told him it's getting out, and she can't have this. She told him they need to cool it for a second and he agreed." For what it's worth, Kimberly's rep told the mag that the allegation is "absolutely untrue."
Apparently, Scott is worried that this could ruin his chances of getting back with Kourtney. If he did hook up with someone after they broke up, that's hurtful, but he certainly wasn't doing anything wrong. The fact that Kimberly is one of Kourtney's friends, that might make things a little more complicated if, indeed, it actually happened.
