Kourtney Kardashian and Scott Disick grabbed dinner together without the kids. The two remain committed to being the best parents they can be to their three children. Things get a little tense. They seemed much more tense that when they arrived. Eyewitnesses at the restaurant said the two seemed to have a very ?serious talk.?and then they argued before leaving the restaurant. Disick was around Cannes making out with models earlier this month. Could they be arguing over that?
