Kim Kardashian showed off the results of her gym workouts for her fans in a few Instagram selfies with her friend, Blac Chyna. 

The 33-year-old Keeping Up With The Kardashians reality star who gave birth to baby North West in July revealed her post-baby body figure, posing in a low-cut cleavage baring sports bran and black leggings. In one photo, Kardashian shows off her big butt looking from the back with Chyna, captioned with a prayer emoji icon. 

In another image, she poses towards the camera, showing off her abs.

"Getting right for the new year," she wrote. 

Though Kardashian's body is back in shape looking better than ever, many have speculated if she got plastic surgery to improve her shape. 

"Unless you're one of the blessed people - and there aren't a lot of them out there, and most of the ones I've seen are Brazilian - very few women look like this after pregnancy... No one has just weight gain in their buttocks, so it seems pretty likely she's had some work done,"Dr. Steve Fallek, a New York City-based plastic surgeon said, according to HollywoodLife.com.

The reality star previously denied on Twitter that her body was fake.

"I worked so hard to train myself to eat right & healthy, I worked out so hard & this was such a challenge for me but I did it!!! I'm so proud of my accomplishment & NO ONE will take this away from me with fake reports! Say what you want about me but I work hard and am the most disciplined person u will be meet!"
