Kourtney has turned the tables on Scott! The 37-year-old dressed down for lunch at Soho Malibu with daddy Disick, birthday boy Mason (who just lost a tooth!) and Penelope but just a night before, she was sexin' it up at the SLS Hotel in Beverly Hills with male model Younes Bendjima -- a hottie she met in Paris a couple months ago.

Benjima, 23, previously dated model Jourdan Dunn but it appears he's moved on!

Baby daddy Scott Disick didn't look too cozy with Kourtney -- no hand on the back, no arm around the shoulders in the cold, windy Malibu weather. Why not? Maybe Scott was privy to the previous night's date? It's not alway fun to get a taste of your own medicine is it, Scott?!
