It's been less than three weeks since news of Kourtney Kardashian and Scott Disick's split [1] and while Kourtney's been out and about [2] looking better than ever, she hasn't yet been seen with Scott — until this week. People reports that on Thursday, Scott and Kourtney met up at the Beverly Hills Hotel [3] with their two oldest children, Mason and Penelope. Additional sources told UsWeekly that the group later left the hotel and went back to Scott's home [4]. While the exes may be staying friendly for their children, it's been reported that Kourtney is still seeking sole custody [5] of the three kids she has with Scott.
