Kim Kardashian is back and hotter than ever before! The reality starlet showed off her curvaceous post-baby body on Instagram, four months after giving birth to her [article id="1709103"]daughter, North West[/article].

The "Keeping Up With The Kardashians" star posed in a barely-there white swimsuit that left very little to the imagination, including her very famous derriere. Her only comment about the sexy selfie was "#NoFilter." While Kim has been out and about since having her daughter, even hitting up [article id="1714773"]Paris Fashion Week with boyfriend Kanye West[/article], this is the most revealing look at her post-baby body.

The photo received a very prompt response from boyfriend Kanye West, who tweeted out "HEADING HOME NOW" in all caps.

For fans wondering how the TV star bounced back after giving birth back in June to her baby girl, she revealed all on Twitter over the weekend, writing, "I've actually been doing the Atkins diet & luv it."

The hot reveal comes just days before she's slated to celebrate her big birthday in Las Vegas. She'll be celebrating the big 3-3 at the Venetian in Sin City on October 25.
