It's been a hungry four years for Megan Fox.

The Transformers babe has her favourite pout-over-the-shoulder look down pat - but seems to be hard at work Transforming everything else.

One of the (many) rumoured reasons that Megan got fired from the action movie franchise was because she got too skinny, with the Transformers crew even commenting on her "gaunt, pale image".

Megan has said that she would "starve to death" before cooking a meal for herself, and has said she drinks vinegar to keep her weight down instead of dieting and exercising.

Considering it looks like she's been messing with her face as well at the tender age of 24, we think it's time for an intervention!
