Kim Kardashian Instagram: Pregnant Mom Posts Nude Selfie, FDA Warns About KK's 'Misleading' Drug Promo

Following speculations that she is faking her second pregnancy because of a photo that showed her non-existent baby belly, Kim Kardashian posted a nude selfie to shut down her critics.

In the post on her Instagram, Kim explained that sometimes, the photo taken of her has to do with the times it was taken. "First they say I'm too skinny so I have to be faking it...Now they say I'm too big so I have to be faking it...SMH! Some days I'm photographed before I eat & look smaller, some days I've just eaten & I look bigger. It's all a part of the process," the reality TV star said in part of her post.

On assumptions that she and husband Kanye West actually have a surrogate, Kim said, "I think you all know me well enough to know I would document the process if I got a surrogate. Everyone's body is different, every pregnancy is very different!"

The star also said that she's nothing but grateful for her body growing at every stage of pregnancy and expects that she will still "even bigger & that's beautiful too!"

The post has earned almost 1.6 million likes and more than 127,000 comments as of press time.

Meanwhile, Kim is embroiled in yet another controversy about her pregnancy when the FDA sent a warning over another Instagram post that promoted her use of Diclegis, the morning sickness drug.

The FDA posted the warning letter they sent a Canadian pharmaceutical company, Duchesnay, Inc,, on their site, saying, "The social media post is false or misleading in that it presents efficacy claims for DICLEGIS, but fails to communicate any risk information associated with its use and it omits material facts. Thus, the social media post misbrands DICLEGIS within the meaning of the Federal Food, Drug, and Cosmetic Act (FD&C Act) and makes its distribution violative."

Parent Herald previously reported Kim's endorsement and the product's safety precautions, which has now been deleted from the reality TV star's account.

The FDA underscored that Kim's post didn't have any mention of the side effects, nor did she say that the medication must be a prescribed by doctors.

The agency has given Duchesnay until August 21 to respond to their warning letter. "Duchesnay is working very hard to take quick action in responding to the FDA's letter and are working out a plan to submit to the FDA," said Laney Landsman, the spokesperson for the company, according to Washington Post.

The drug company also confirmed that Kim was paid to advertise her use of the Diclegis, according to CNBC.
