She stunned fans earlier this year when she displayed her incredibly slim frame.
But Megan Fox has revealed her slender figure was down to a strict vegan diet, which she has now ditched after losing too much weight.
Recent photos of her on set for her next flick, Dication, show that she's back to a healthy looking Megan. Looking relaxed in leggings, and a loose tee, Megan's shape is looking amazing, rather than scarily-thin.
The former Transformers star revealed in a recent interview with Amica magazine that she was shocked into giving up her vegan diet when she realised how much weight she had lost.
She said: 'For a year and a half, until about four months ago, I followed a strict vegan diet based on raw fruits and vegetables, no bread, sugar and coffee. But I had lost too much weight.
'So now I eat a bit of everything. And I train three times a week doing circuit training with my trainer Harley Pasternak.'

Meanwhile, Hollywood fitness king Pasternak has since revealed that Megan is now following his 5 Factor diet, which sees the dieter eat five small meals a day combined with 25 minutes of exercise broken down into five five-minute sessions.
He told Starlounge UK: "She follows the 5-Factor diet which is to eat five small meals a day which include the five dietary factors including healthy fats, lean protein, fibre and a non-sugar drink.
"If she needs to snack between meals then she has our 5-Factor crisps which keeps her satiated between meals."
Referring to what he and Megan do to help maintain her curves, Pasternak added: "Megan wants her body to reflect who she is. She looks awesome. She’s natural, softly spoken and her personality shines through her fantastic shape.
"Megan’s also lucky because her husband Brian Austin Green follows the same workout routine. They share the same enthusiasm for a healthy lifestyle which is fantastic too."
