We're sure this product had everything to do with her ripped physique... not!

Khloe Kardashian showed off her unbelievable body in nothing but jeans and a bra while promoting Flat Tummy Tea on Instagram yesterday, and we can't believe how much weight she's lost since giving birth!

"#ad Loving how my tummy looks right now you guys! I brought @flattummyco’s meal replacement shakes into my routine about 2 weeks ago, and the progress is undeniable✨P.S the shakes are 20% off today and you can get Flat Tummy Tea at a really good deal too. Go check it out!" she captioned the post.

Some fans aren't too happy she's plugging brands that might be dangerous to your health, and one of those people is The Good Place actress Jameela Jamil.

“If you’re too irresponsible to: a) own up to the fact that you have a personal trainer, nutritionist, probable chef, and a surgeon to achieve your aesthetic, rather than this laxative product… And b) tell them the side effects of this NON-FDA approved product, that most doctors are saying aren’t healthy. Side effects such as: Possible Flat Tummy Tea side effects are cramping, stomach pains, diarrhea and dehydration… Then I guess I have to," she commented on the social media site.

"It’s incredibly awful that this industry bullied you until you became this fixated on your appearance. That’s the media’s fault. But now please don’t put that back into the world, and hurt other girls, the way you have been hurt. You’re a smart woman. Be smarter than this," she added.

We want to know what she's really doing to get these rock hard abs!
