During a recent interview, Kim called herself "heavy" and said in a blog post that her body has become "awkward."
What's more, Kim is reportedly worried that boyfriend Kanye West wants a woman with a better body and that he'll be tempted to go behind her back to get it.
As sad as it is, Kim might have a legitimate concern. Sources did report that Kanye seems to be "trying to get away from her" lately and that his passion for Kim "has cooled."
Kim even confessed that some of her 17 million ever-adoring Twitter followers have started taunting her about her weight gain.
"People can be so mean," she told Us Weekly. "It's not cool and it's not fair. People are saying, 'you're so fat!' I'm like, dude, I'm pregnant! Social media gives people the guts to say mean things."
Also, on a recent episode of Kourtney and Kim Take Miami, Kim helped her sister Kourtney cope when her boyfriend Scott Disick was complaining about the weight she put on while she was pregnant.
All of this could explain why Kanye's better half has been hitting the gym a little too hard lately.
Hopefully Kim can put her weight issues aside for the sake of baby Kimye.
Are you surprised that Kim is suddenly self-conscious?
