Scott Disick May Have Hooked Up With Kourtney's Friend Kimberly Stewart

It seems, sometimes, Scott Disick's greatest fear is another celebrity out-awfuling him.

In a concerted effort to maintain his status as the Hollywood villain no one particularly fears or respects, Disick reportedly got way sexy with Kimberly Stewart on multiple occasions.

A source claimed,

It was going on for several weeks… Kimberly knew it was wrong, but couldn't help herself… 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.

Stewart is a friend of Kourtney Kardashian, who recently grew tired of Disick's sh*t for the 900th time.

The source added,

[Disick] feels like an assh*le… He was trying to get Kourtney back, but he is hoping she doesn't find out. He's kicking himself.

Kardashian and Disick share three children and a history of dramatic arguments.
