Posh-thin Megan Fox has admitted she was ordered to pack on ten pounds for her role in the Transformers sequel, says Us.

“I’d lost a lot of weight and got really scrawny, but I was told I had to put on size for Transformers because [director Michael Bay] doesn’t like skinny girls,” the 22-year-old actress told the FOX Television Critics Association party yesterday.

Maybe Megan should hang out with her co-star Josh Duhamel's fiance, Fergie, who know all about lady lumps. She also knows about getting decked out in skank gear, but that's probably research for a whole other movie.
