Taking to Instagram, Khloe wrote a lengthy promotion post for Flat Tummy's Shakes, and it's, er, questionable.
"#ad Okay... LISTEN UP. I’ve posted with @flattummyco’s Shakes many times in the past and YES, I also use a personal trainer and a nutritionist. But seriously you guys, everything counts. THESE SHAKES WORK to help get your tummy back to flat, especially after a super busy holiday season, and that’s exactly what I’ve been doing."
Khloe continued: "If you want to start 2020 off right and get back on track, their New Year, New Tummy Sale in full swing. Trust me you guys… go get 25% off the same Shakes I drink @flattummyco 💕"
Fans were SERIOUSLY unimpressed with Khloe post, calling the advertisement 'disappointing' and 'irresponsible'.
