Kourtney Has Laid Down New Rules For Scott

Kourtney Kardashian and Scott Disick are fully back on track as co-parents after some serious conversations and a little family vacation.

Sources in the know of the new development say Kourtney laid out the rules loud and clear to Scott - if things are gonna work, there's no more hard partying and he's gotta respect her dating someone else. So far, Scott's obliged and things have gone swimmingly.

The pair recently spent some time in Nantucket with their 3 kids. Sources say they have realized the importance to make their children know despite no romance they can get along.
