He can't keep it in his pants long enough for Kourt to forgive him!

Scott Disick is technically a single man, but that doesn't mean that his recent hookups with Kourtney Kardashian's former pal Kimberly Stewart are going to go over so well!

The father-of-three and the Stewarts & Hamiltons star have had several secret flings in the months since he was dumped by the eldest Kardashian, Us Weekly reports. The Lord was keen to keep the trysts quiet, but word has gotten out and it is bound to kill any hopes of a reconciliation with his ex-partner and children.

"Kimberly knew it was wrong, but couldn’t help herself," a source dished to the mag, although her rep blasted the report as "absolutely untrue."

LD is actually feeling guilty about his behavior, but it remains to be seen if he can smooth things over. "He feels like an a**hole. He was trying to get Kourtney back and was hoping she didn’t find out," the source added.

When is he going to learn that you can't get away with anything when you're famous?!
