Kim Kardashian flaunted her post-baby body online.

The 'Keeping Up with the Kardashians' star has been trying to shift her pregnancy pounds after having daughter North in June - her first child with boyfriend with Kanye West - and was pleased to share the results of her gym sessions and Atkins Diet with her fans.

The brunette beauty posted a revealing 'selfie' photo on her Twitter page, linking to her Instagram account, in which she wore in a one-piece white swimsuit which showed off her curves and small waist.

The 32-year-old reality TV star captioned the image ''#NoFilter'', a reference to the photo sharing website's photo enhancing tools, implying the picture had not been altered.

While thousands of Kim's fans were quick to comment on the saucy snap, her boyfriend Kanye was delighted with what he saw responding: ''HEADING HOME NOW''.

Kanye is reportedly joining Kim on the Atkin's diet which promotes reduced carbohydrate intake while encouraging the consumption of healthy fats, proteins and cheese.

The same diet has been popular among a number of other A-Listers including Rihanna, Sharon Osbourne, Jennifer Aniston, Demi Moore and Catherine Zeta-Jones.

At the height of its popularity in 2003, about three million people in the UK had tried the diet and in America one in 11 was reportedly on it.
