They've got this co-parenting thing down!

Kourtney Kardashian and Scott Disick took their three children to lunch in Malibu on Sunday, and just hours later, the mother-of-three hopped on a flight bound for London. It looks like The Lord is on daddy duty while his ex is away.

Just one night prior, the former couple took their brood to the Hollywood Bowl to see the live concert performance of The Little Mermaid, and you just know LD would have rather been partying with hot chicks on a yacht in St. Tropez!

Kourt was preoccupied with banging Justin Bieber for a while, but now that The Biebs has left her in the dust, we gotta wonder if she's contemplating taking her baby daddy back? She's never going to do better than him, and her wretched personality is going to make dating pretty challenging!
