She's the controversial vegan blogger who's known for her unusual eating habits.
And the fitness star, who hails from Queensland, shared a throwback picture of herself as a teenager before undergoing a 'clean eating' transformation.
Taking to Instagram, the retro photograph shows the young woman smiling at the camera with a noticeably fuller figure.
Now, the Australian social media influencer, who has more than 400,000 Instagram followers, looks unrecognisable - so can you guess who she is?
'Me at one point when I was younger and definitely not as happy,' she wrote in the caption.
The image shows vegan advocate Leanne Ratcliffe, also know as 'Freelee the Banana Girl', before she switched to a raw plant-based diet.
She's famously known for eating up to 51 bananas and two kilograms of potatoes in a day while sticking to raw food until 4pm.
Earlier this month, the now 37-year-old insisted her weight loss came after she ditched a paleo diet to become a vegan.
'On the left I was eating a paleo diet, low carbs with excess protein and fat causing a bunch of terrible health problems,' Leanne on her Instagram.
'At an age where I should have been my happiest and healthiest I was constantly depressed, lethargic, had CFS and irritable bowel syndrome, brittle nails, constant thrush, cystic acne and low thyroid function to name a few.'
The social media sensation reveals she has since lost a total of 18 kilograms since ditching paleo and going vegan and 'healed' her digestive system through her excessive clean eating.
Flashing her lean stomach and toned abs in her 'after' photo, Leanne says her skin is now radiant, her hormones are in check and she is no longer depressed - adding she is now fitter at the age of 37 than she was at 20.
But according to Freelee the Banana Girl, the biggest victory in adopting veganism is no longer taking the life of 'innocent' animals for her meals.
'I no longer eat my friends or byproducts that cause them pain and suffering,' Leanne added.
'Please never forget the voiceless victims of your meals.'
The vegan blogger first rose to internet notoriety after claiming to eat 51 bananas a day and starting a war with fellow Instagram star Kayla Itsines.
She claims an extreme, low processed, low-fat, high-carb raw vegan diet - including an vast daily consumption of bananas - is the key to gut health and her ultra-slim physique.
Freelee remains ‘raw until four’ - meaning she eats no cooked or heated food whatsoever until 4pm - and blends up to 20 bananas daily into smoothies.
Leanne discovered raw veganism in 2001 and often tells her legion of fans that it saved her life.
'This lifestyle saved my life and now I'm so grateful to help do the same for girls around the world,' she wrote on Instagram.
