The youngest Kardashian sister has no qualms exhibiting her curves on Instagram or in public for that matter. Kylie Jenner posted a photo on Thursday of a night out with Tyga. In the pic, the 19-year-old shows off her abs and a good sampling of her lingerie under her crop top. She rolls her eyes and holds the sides of her head looking unimpressed while Tyga stands next to her grinning.

"Walk up in this bitch like..! That eye roll tho," the caption reads. The photo has already gained more than two million likes, which isn't surprising for the IG model with her 84.4 million followers.

The Kardashians are currently on a family vacation in Costa Rica. No word on where or when the pic was taken.
