Kim Kardashian gives whole new meaning to the phrase "Baby got back!"

You'd NEVER know that the reality star had a baby four months ago thanks to the smoldering and sexy snap she shared on Instagram, showing off a bit of sideboob and that famous booty of hers while wearing a white bikini. That's some serious junk in the trunk.

She's blonde. She's back. And baby got back! Her tanned skin really pops against the stark white bathing suit.

Dayum, she looks fine. We'll go ahead and say it. Kimmy K. is one hot mama.

Kardashian must have been working overtime to return to her pre-North West figure. She's also dethroned Jennifer Lopez as the booty queen with one picture.

Yeah, that thing is on Nicki Minaj-like levels of shapely.

Kanye West, her baby daddy, is a very lucky man.

Yeezy even tweeted his reaction to the photo! Steamy!
