Even though it didn't take long for Kim Kardashian to lose most of the baby weight, the soon-to-be Mrs. Kanye West admitted that her New Year's resolution for 2014 is to lose more weight! 

According to The New York Daily News, Kardashian -- who gave birth to North West last June -- was spotted back in the gym with stripper-turned-rapper's-wife Blac Chyna. Of course, they posted their booty-licious pictures on Instagram, with the caption "getting right for the New Year."

While Kardashian does have a ways to go before she's fully back to her pre-baby weight, she did look good with a toned tummy and tight rump.

"Chyna, a model and former stripper, is engaged to rapper Tyga. Like Kardashian, she also has a little one at home, named King Cairo Stevenson. Kardashian's New Year's resolutions may include wedding planning. The E! star got engaged to boyfriend Kanye West last year, just months after welcoming their first child," reports the Daily News. 

And, according to Hello! Magazine, it's not just the change in the exercise regimen that's got the Keeping Up With The Kardashians star in good physical shape: she's also re-started the Atkins diet, the low-carb alternative that is popular amongst the Hollywood elite. "With the exception of some cheat days, because she is realistic now, she sticks with it! Kim is working out almost every day. It's usually running and weight training. It's hard, but she sticks with it pretty much all the time. She's so happy. Life is good," reports Hello! 

This latest round of postings comes in response to the reports that Kardashian went under the knife to lose her baby weight. "I am very frustrated today at seeing reports that I got surgery to lose my baby weight. This is FALSE. I worked so hard to train myself to eat right & healthy, I work 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 u want about me but I work hard & am the most disciplined person u will ever meet!" she wrote on Twitter.
