Celebrities, models, celebrating their cellulite on Instagram in body positive movement

Demi Lovato has become the latest celebrity to celebrate her cellulite by posting an unedited picture of herself to Instagram in a bid to squash her "biggest fear". 

In a lengthy post, the former Disney star admitted to editing previous bikini pictures, saying she was "so tired" of being ashamed of her body. 

"I'm literally so tired of being ashamed of my body, editing it (yes the other bikini pics were edited but that's the truth) so that others think I'm their idea of what beautiful is, but it's not me," she wrote. 

Lovato ended the post with a disclaimer. 

"Just so everyone is clear…I'm not stoked on my appearance but I am appreciative of it and sometimes that's the best I can do. I hope to inspire someone to appreciate their body today too," she wrote. 

Lovato then hashtagged the post with ' #celluLIT', a hashtag which has encouraged over 20,000 people to tag their body-positive posts with the phrase. 

Lovato is not the first celebrity to speak out about owning the skin you're in, and she hopefully won't be the last. 

A number of celebrities have spoken out in recent years about body positivity, hitting back at paparazzi who stalk celebrities just to get a glimpse of dimpled bums. 

Fellow Disney star Hillary Duff shared a photo taken of her from behind, while on holiday with her son. Duff shared the post as a "message to women of all ages". 

"Since websites and magazines love to share 'celeb flaws' - well I have them! My body has given me the greatest gift of my life: Luca, 5 years ago," she wrote. 

"Ladies, let's be proud of what we've got and stop wasting precious time in the day wishing we were different, better, and unflawed."

Model Ashley Graham has always been a loud advocate for body positivity, and made headlines last month when she posted a candid photo of her growing pregnant body on Instagram.

The 31-year-old captioned the raw image with "same same but a little different." 

The "inspirational" photo was met with an emotional response, with one fan writing the post had made her tear up. 

"I'm such a wimp. I'm pregnant, hormonal, and going through so many body changes. "This made me tear up. I really needed this today," they wrote. 

Australian model and business owner Steph Claire Smith has also become an advocate for body positivity as of late, pushing against the idea of perfection. 

Smith shared an Instagram post in May, asking why we care so much about lumps and bumps. 

"I've got lumps and bumps I used to hate myself for..and why? Why is it we care so much, why do we chase perfection so much when it doesn't exist?" the 25-year-old wrote. 

"Look after yourself, appreciate your body for what it can do, not what it looks like."
