Lizzie recently took to her Instagram to upload a body shot, showing off her new figure while promoting a booty mask, however fans were loud in the comments about how concerned they are for her.
"Seriously you're to [sic] skinny. Eat something 🤮🤮🤮🤮🤮🤮" one fan commented.
"And I ain’t being rude as I do admire her and her strength but it’s worrying," another said.
Another follower wrote: "Wow I love you but you don’t look healthy."
It comes after Lizzie shared an incredibly slim selfie on Valentine's Day.
"Way toooo thin now," one person wrote.
"You so thin!" another said.
"Are you well?" said another.
Lizzie has lost a huge ten kilos since first appearing on MAFS in 2019, where she was famously fat-shamed by her TV husband Sam Ball.
Elizabeth does insist that her major weight loss is from an illness, and not any kind of diet.
Speaking previously to an Australian magazine, she said that she had lost the weight because of an auto-immune condition similar to lupus.
The star is set to appear on MAFS 2020 in the next week, coming in as an intruder.
