Scott Disick who?

Kourtney Kardashian stepped out with son on Saturday, and despite the fact that she's raising three children on her own and dealing with the aftermath of her nasty split from Disick, she seems to be doing just fine. From the smile on her face to her uber hot revenge bod, we're beginning to think it's less and less likely that the two will ever reconcile...

And not only that, but HollywoodLife reports that Kourtney already reached out to Scott's new fling, 18-year-old model Lindsay Vrckovnik.

“As far as Scott’s new relationship with Lindsay is concerned, Kourtney’s message to her is ‘You’re welcome to him,'” a source tells the site. “When Kourtney saw how old Lindsay was, she just laughed. She thinks it’s embarrassing he’s hanging out with such a young girl and shows just how insecure he is. She thinks Scott believes he looks cool dating a young model, which is a bit of a cliche for a wealthy man approaching their mid-thirties."

And you know what? We totally agree...
