The 28-year-old, who made history earlier this year (16) as the first non-traditional model to feature on the front of the Sports Illustrated Swimsuit Issue, drew attention from her social media followers after posting a photo on Instagram which appeared to make her look thinner than usual.

In the snap she shared on Wednesday (20Jul16), Ashley was shown wearing a white crop top, matching skirt, and black leather jacket, seemingly showing off a slimmer frame.

But she received backlash from followers who looked up to her for her usual plus-size pictures, with one writing, "What happened to embracing your size? You advertise that message then go and lose weight?? I mean hey more power to you, but idk (I don't know)...puzzled," while another, angrier user wrote, "I knew it you did lose a lot of weight! I am no longer a fan of yours you betrayed a lot of people! So I'll find another plus size beautiful woman bcuz your (sic) full of S**T!!! #damnshame #justliketherest."

However, Ashley has since responded to the haters in the comments section of the photo, noting she can never satisfying anyone, no matter what size she is.

"People come on my page and body shame me because I'm too big, because I'm too small, because I'm not good enough for their standards," she wrote. "But at the end of the day I'm good enough for me. Angles will make anyone look bigger or smaller and I just happen to know mine."

She also took to Snapchat to further explain herself, posting a video showing her walking down a runway in lingerie.

The caption read, "I will not let others dictate what they think my body should look like for their own comfort, and neither should you."

Her response to the online critics comes after it was revealed she will be a new judge on the upcoming revamp of America's Next Top Model.

Ashley will be joined by Paper Magazine Chief Creative Officer Drew Elliott, and celebrity stylist Law Roach, while Rita Ora will also serve as the host.

The pop star replaces the show's creator Tyra Banks as presenter; she stepped down from the gig after its 22-cycle run ended in December (15). Bosses at America's CW network cancelled the show, but chiefs at the VH1 network opted to pick up the series for its 23rd season.

Tyra Banks will continue to serve as executive producer and make appearances throughout the season.
