A post shared by Kim Kardashian (@kimkardashian)A slew of Instagram followers claimed she edited out her belly button. "You forgot to leave in your belly button!" one person alleged. Another wrote, "Where on earth is your belly button?"As fans and even media reported on the belly brouhaha, Kim clapped back. "Come on guys….Seriously! This is so dumb!" she wrote. "Claiming I Photoshopped out my belly button????"In a separate post, she implied that her shapewear line covered up the body part, and, ever the businesswoman, she even used the moment to hype up the benefits of Skims."Belly button insecurities?! why don't you head over to skims.com to conceal that saggy belly button of yours with a great pair of high waisted underwear like I did!" she wrote.
