She can't stop and she won't stop! Kylie Jenner loves a good belly-bearing selfie and she's NOT gonna stop posting them ... thank god!

The new mom is determined to prove to the world that she's lost her baby weight after giving birth to daughter Stormi just over four months ago and she's documenting her weight loss in a series of sexy crop top selfies on Instagram.

Saturday night she posted a shot with BFF Jordyn Woods (who's also dropped a fair number of pounds recently) with the caption "piercings." What?! Where? We're afraid to ask ...

Earlier in the day she uploaded some snaps of herself laying in the bed of an Airstream, it appears, wearing a striped bandeau top that accentuates her massive, almost porn-star level cleavage. We get it, Kylie! You can be a mom and still be sexy! Noted!
