Kylie Jenner Flaunts Smaller Butt in New Instagram Shot — See the Pic!

Has she downsized?!

Kylie Jenner showed off her derriére in a skin-tight jumpsuit on Feb. 11 — but her usually perky butt was seemingly tinier!

The 18-year-old's killer curves and bigger assets are speculated to be the result of plastic surgery, but the raven-haired beauty has denied claims of going under the knife.

Don't forget, she once lied about her oversized lips before finally confessing to having lip injections.

So — does her smaller booty prove that the reality star gets injections in places other than her lips, or does this jumpsuit just magically make everything appear smaller?!
