The 38-year-old Keeping Up With The Kardashians star took to social media over the weekend and dropped an x-rated shot of his 19-year-old girlfriend, model Amelia Gray Hamlin.
The photo -- which has been labeled "inappropriate" by some -- showed Real Housewives of Beverly Hills star Lisa Rinna's daughter nearly in the nude.
Snapping a shot from behind showing Amelia stretching while wearing a skin-colored thong that exposed her plump derrière, Scott was clearly enjoying his view.
The teen was above ground level, climbing on a shelf to grab something, and wasn't wearing anything except the nude and lacy thong and teeny tiny bra.
Scott -- who hardly ever shares anything about his romance with Amelia on social media -- has been dubbed "creepy" for showcasing her body, instead of her face.
His caption may have added to that.
It's an interesting move considering his ex Kourtney is all about the PDA-filled pics with her new boyfriend, Travis Barker.
The former couple shares three children -- sons, Mason, 11, and Reign, 6, as well as daughter, Penelope, 8.
Kourtney shocked everyone when she went public with her romance earlier this year.
Since then, she's proved she can't keep her hands off the Blink 182 drummer.
The KUWTK star and her rocker beau made jaws drop when they shared racy photos from a romantic getaway in April.
Kourtney and Travis unplugged from their chaotic lives to romp around in the desert together.
She showcased their magnetic chemistry by posting a photo showing herself jumping into her boyfriend's arms and planting a fat one on him.
Here's the kicker -- Kourtney wasn't wearing anything except an itty bitty metallic bikini top and matching thong.
Eyes immediately went down south, focusing on her famous booty.
They've only continued to turn up the heat and haven't shied away from PDA, something that another ex isn't too happy about.
As RadarOnline.com reported, Travis' ex-wife Shanna Moakler slammed the couple and claimed the rocker was copying the relationship they once shared.
