Kourtney Kardashian and baby daddy Scott Disick met face-to-face for the first time yesterday since Kourt's been spotted out on the town with a new beau ... so we wonder exactly what went down inside the studio as the family taped KUWTK.

But let's get real -- Scott's no stranger to dating younger people. His current g-friend Sofia Richie is 15 years his junior and the dude Kourtney went out with over the weekend, David Dee Duron is a sprightly 26 -- a mere 13 years younger than the eldest Kardashian sister! So there's no way Scott can have any issues with his ex's dating life, though he probably does. The notoriously possessive Scott seems to always find a way to date who he wants to, be as unfaithful as he cares to and still get jealous with his significant other -- or even his FORMER significant other -- has a boyfriend.

In addition to dating younger people, there's another thing Kourt and Scott have in common ... it's their love of luxury vehicles. Scott's probably the most guilty when it comes to balling on balls-out cars but even Kim and Khloe have gotten in on the game. All told, Kourt owns an insane Astin Martin; Scott's currently driving a Bentley; Kim's got a custom-painted 2019 Range Rover; and Khloe's now in a BRAND NEW Rolls Royce SUV! That's more than $1 million on vehicles right there!
