Scott Disick, Kourtney Kardashian -- Together Again Briefly ... for the Kids

Scott Disick and Kourtney Kardashian kept it civil Thursday, when they had a meal together with the kids.

Scott, Kourtney, Mason and Penelope all had lunch at the Beverly Hills Hotel. We don't know if baby Reign was there.

After lunch, they drove in separate cars to Scott's Hollywood Hills home where she handed off the kids so he could spend time with them.

As we reported, Kourtney was at a Century City building Monday, and although we don't know who she saw, it's the building where attorney Laura Wasser works. She repped Kim and Khloe in their divorces, and we know Kourtney wants to work out a custody arrangement.
