Why does this feel so pervy?! Oh wait, because she's a teenager!

Scott Disick filmed his girlfriend Sofia Richie dancing in her underwear in his kitchen and put it on Instagram, and we're at a loss for words. The model grooved along to her dad Lionel's hit "All Night Long," and her boyfriend was loving the show so much, he thought he'd share it with his followers.

We're sure we'll see a lot more of this kind of stuff if the reality show they're filming gets picked up. Yes, apparently the duo want their own spinoff and have already got it in the works.

We know that Kourtney Kardashian isn't going to let LD bring his lady love to the family Christmas party, so we wouldn't be surprised if he ditched it entirely and spent the holiday with the Richie clan!
