Scott Disick -- Fits Parenting Into Busy Schedule (PHOTO)

Scott Disick took a break from partying, rehab hijinks, and then partying some more to spend time with two of his kids, Mason and Penelope.

Disick and the kids hit up a sushi joint Tuesday in Calabasas.

Disick bailed on his trippy Costa Rican rehab this week and came back to L.A., but not before some serious Costa Rican clubbing. He's already booked a club appearance in Vegas for this weekend at 1 OAK in The Mirage Hotel & Casino.
