An Instagram star and a fitness lady has surprised the entire social media by posting enviable bikini snaps while (9) nine months pregnant.

With her incredulous toned tummy, no one on earth would ever believe or guess that model Sarah Stage is even pregnant, talk more of (9) nine months. The Los Angeles Instagram star, 33 year old, posed a saucy selfie in a bright red bikini.

In the photos she shared on Instagram, she proudly held her tiny bump tummy, which is barely visible in the images.

Unsurprisingly, Sarah's followers were very surprised by the mum's appearance.

How this is possible amazes me! I look like I've eaten a watermelon haha! Xx, one of Sarah's followers remarked.

Other of her fans also got involved in the serious discussion, like one Instagram user said:

Another user said:

One critic said:

I'm a nurse & you are so scary... dieting & extreme exercises... I hope you & your baby are normal after what you put your baby through!
