Ashley Graham is not here for body shamers. The model fires back at a rude commenter for asking whether she's pregnant on social media.

Doing Her Thing

 America's Next Top Model alum Graham took the issue with a comment on a video she posted of her dancing around in a pink bikini to N.E.R.D. and Rihanna's "Lemon" while on vacation.

A wannabe troll claimed that Graham had a noticeable baby bump in the clip. The model, who refuses to be shamed for her curvaceous figure, clapped right back to let the person know what's up.

"That's just called fat," she replied simply.

Fans of the body positive star quickly rallied to her defense, pointing out among other things that Graham isn't even fat, to begin with. Another thanked the model for helping women of all sizes to feel better in their bodies, encouraging her to keep doing her thing.

Body Positivity

Graham is a vocal body positivity activist. Just a couple years ago, she penned a lengthy essay about loving yourself no matter what, taking particular issue on social media and online bullying.

"To some I'm too curvy. To others I'm too tall, too busty, too loud, and, now, too small -- too much, but at the same time not enough. When I post a photo from a 'good angle,' I receive criticism for looking smaller and selling out. When I post photos showing my cellulite, stretch marks, and rolls, I'm accused of promoting obesity. The cycle of body-shaming needs to end. I'm over it," she wrote at the time.

The Sports Illustrated model went on to note that she's not who she is because of her curves, her measurements, or anything else physical. Graham encouraged those reading to worry about themselves only and to support other women to own their beauty also.

No Time For It

In October of last year, she hit back, again on Instagram, at fans criticizing her for posting workout videos. Graham has been open in the past about being dumped by boyfriends who were terrified she'd one day get too fat.

She also happily told Glamour in a 2016 interview that she was giving the middle finger to haters who criticize her body.

"I kind of just give my middle finger to [haters], like, 'Guess what? I'm really hot. Every day I get at least 20 messages [saying I've helped them]. I hope they look in the mirror and say, 'I am beautiful.' When you do that ... you start to understand that your words have power," she said at the time.

The ANTM alum is a proud advocate for mantras, revealing previously that she tells herself in the mirror each morning that she is beautiful.
