The 27-year-old - who released a fitness DVD in 2017 after losing an impressive three stone - took to Twitter last night to express her thoughts on the matter.
'Tell me the size I should be please! I got slated when I slimmed down to a size 8 and I get slated when I'm a size 12,' she stated.
'So please let me know what measurements I should be. And they wonder why young women are reduced to surgery!'
The TV star's tweet quickly gained traction, with over 50,000 followers 'liking' it and many sending a reply.

Fans praised Scarlett for speaking out, with one saying: 'The size you are. Or the size you were. Or the size you will be. Whatever size lets you live your life and be happy in yourself. That's the perfect size for you.'
It wasn't just fans who felt the need to voice their support for Scarlett, a number of individuals in the public eye did too.
'You are beautiful,' Loose Women star Nicola McLean said, while fellow TV presenter Gaby Roslin tweeted: 'I'll say it again and this time I'll shout it! YOU ARE BLOODY WONDERFUL.'
International plus size model Louise O'Reilly also typed out a reassuring message for Scarlett.
She wrote: 'Never let media or other people define your size or self worth... I know it's hard but you are amazing at what you do - by being you 💖.'
Scarlett found fame while appearing on the Channel 4 show Gogglebox. She went on to win the 16th series of I'm A Celebrity... Get Me Out Of Here! in 2016.
In 2017, it was announced that the star from County Durham would host the I'm A Celebrity spin-off show Extra Camp.
