Scott Disick appears to be well aware of what he lost this summer.

A couple days after Kourtney Kardashian posed naked for a Vanity Fair shoot, her ex-boyfriend and perpetual baby daddy went ahead and made it clear how he still feels about the reality star … by posting the photo of her nude.

"Now that’s 1 hot mama," Disick captioned the birthday suit-based picture of Kourtney, sharing it with Instagram followers on his own account.

A little weird? Yes. A little flattering? Sure, we guess.

Perhaps one reason Disick feels confident gushing over his longtime partner, however, is because he’s moved on in his romantic life.

The douchey star has been spotted out and also about with 18-year old model named Lindsay Vrckovnik over the past couple weeks.

She claimed the two are merely friends, but we’ve heard that line plenty of times in the past. Specifically from Chloe Bartoli.

"He’s very removed from [the family man] part of his life," a source recently told Us Weekly of Disick. "He’s been going wild."

Sort of like what this smoking hot MILF has been doing on Instagram in an attempt to rub her hot body in Scott’s face. To wit:
