Just last week, it seemed Scott was moving on with a MUCH younger girlfriend, but he's just let slip that he's definitely not over Kourtney.
The dad-of-three took to Instagram last night to post a very telling photo, which suggests he might be missing his ex.
"Now that's 1 hot mama," he wrote, alongside a snap of a naked Kourtney lying on her side and covered in metallic paint.
Kourtney herself shared the image earlier this week as part of photographer Brian Bowen's Metallic Life series. Her snap is currently on display in a Los Angeles art gallery along with several others.
Scott's post is the first time he's made a reference to Kourtney on social media since the split, and he couldn't have chosen a more obvious way to say, "I want you back."
Two days age he shared another photo, this time of an outdoor swimming pool which many noted looked very similar to the one in Kourtney's back garden in Calabasas, California.
Of course, Scott may have just been there to visit with his kids – five-year-old Mason, three-year-old Penelope and ten-month-old Reign – but either way it suggests he's missing his former life.
Scott was linked to 18-year-old model Lindsey Vrckovnik last week after the pair were pictured together in both New York and Miami.
But days later the Canadian model spoke out to say she had a boyfriend and flat-out denied to TMZ that she and Scott had hooked up.
As for Kourtney, she appears to be having a crisis of conscience, breaking down in a new episode of KUWTK filmed shortly before her split from Scott.
"I wanna be mad but then I also worry about Scott's safety, he definitely has a problem that he has to deal with, so it's hard," she said.
"I feel like my emotions get all over the place."
