Sara Sampaio has made a career out of her long, lithe limbs, the face - and body - of Victoria's Secret and Sports Illustrated among many other big-name brands.

But sharing a photo of her bikini-clad body on Instagram on Wednesday ahead of taking to the catwalk as part of the annual Victoria's Secret Fashion Show extravaganza, she took the opportunity to hit out at haters she accused of 'bullying' her.

The 23-year-old Portuguese beauty declared to her more than 700,000 followers that she's 'proud of my body' as she added, 'I'm not gonna let any of you bully me just because I'm skinny!'

'I'm not gonna let any of you bully me just because I'm skinny!' Victoria's Secret model Sara Sampaio took to Instagram on Wednesday to hit back at 'body bulllies' as she shared this sexy bikini selfie with fans

'Every body is different, and every metabolism is different!' she explained of her naturally-slim frame. 'I eat a lot, so next time u decide to tell me to eat a burger remember I probably eat more burgers than you, I've always been skinnier, and probably will always be, I workout, I'm healthy and I'm happy!'

Clearly not new to facing criticism for her pin-thin figure, she lashed out at not only those who aim negative comments at her, but also at her fellow model pals.

'The amount of hate I see thrown at me and to other model friends that I know are naturally skinny it's ridiculous! U don't see us shaming other types of bodies so please don't come and shame ours (sic)!' she wrote.

'Every body is different, and every metabolism is different!' The 23-year-old Portuguese beauty declared, 'I eat a lot, so next time u decide to tell me to eat a burger remember I probably eat more burgers than you'

Wanting to spread a message of love and acceptance for every type of body, whether big or small, she ended on the note that hate isn't something that should be shared around.

'Be happy with ur body and stop shaming others! Whether they are skinny, fat, fit, with big boobs, small boobs etc! Don't share hate! Be happy.'

Sara's post comes in the wake of Victoria's Secret changing their recent 'The Perfect Body' underwear campaign slogan to the more inclusive 'A Body For Every Body' after copping criticism.

'I workout, I'm healthy and I'm happy!' The model, who is known for her extensive work with Victoria's Secret and Sports Illustrated, among others, delivered the body-confidence message, 'Whether they are skinny, fat, fit, with big boobs, small boobs etc! Don't share hate!'

Following the backlash, the lingerie giant shared a short video of Sara on Instagram talking about how everyone's bodies are different and perfect in their own way, saying that she herself wishes she looked like fellow VS Angel Candice Swanepoel but her bone structure simply wouldn't allow it.

Picking up the story, Jezebel called the model out on setting feminism back with their article titled Helpful Victoria's Secret Reminder: Even Models Hate Themselves.

'The video is packaged as though it's supposed to encourage women to accept and love themselves, but it's really just one model talking about how another model is so totally sexy in an unobtainable way,' they stated.

Not taking it lying down, Sara was quick to respond with a very lengthy Instagram post.

'Dear Erin from Jezebel, I don't hate myself! I was actually taught by my family to respect and love myself and indeed others!' she began.

She went on to call them out on 'creating a negative spin on a positive message'.

'The title of your article states that I hate myself. To the contrary I love myself like I am,' she wrote.

Hitting back! After Jezebel criticised Sara for a video entitled 'Know your body' shared by Victoria's Secret in an article called Helpful Victoria's Secret Reminder: Even Models Hate Themselves on Friday, she responded with a strongly-worded message about how women should 'stand together'

'I can also look at another woman and admire her beauty... It doesn't mean I want to look like them because I am happy the way I am, the way my mother and father brought me into this world, and who I am today and who I will be in the future.

'You are a beautiful young woman, please love yourself and don't judge other women that you don't know,' she finished. 'As women we need to stand together. We are judge and objectified often enough by men. Here is to your feminism.'
