Kim Kardashian Claims 20-Pound Weight Gain on Twitter

The newlywed and mother-of-one revealed via Twitter on Tuesday morning that she’s packed on a few pounds since marriage and motherhood.

“Off to an intense workout. Can’t seem to shake this last 15-20 lbs. of baby weight. No more excuses. my baby is 1 years old! UGH,” the 33-year-old wrote. “I’m not gonna call it baby weight bc that’s an excuse. I just gained weight & that’s it. Why is it so much harder to lose after baby though?!!”

This news may come as a shock to those that saw the Keeping Up with Kardashians star on Jimmy Kimmel Live Monday night. Looking as svelte as ever, Kim donned a form-fitting outfit for her appearance on the late-night show, and made no mention of her weight gain.

I’m not gonna call it baby weight bc thats an excuse. i just gained weight & that’s it. why is it so much harder to lose after baby though!!
