The world’s sexiest female Megan Fox, has been ordered to gain weight for the up and coming Transformers sequel, because she’s too skinny.

Transformers director Michael Bay has told Fox to add 10 pounds to her frame before she starts shooting the sequel later this summer.

Fox, who topped Fhm’s annual poll of beauties, recently slimmed down for her role in the upcoming film Jennifer’s Body.

The 22-year-old star told Fox News,

“I’d lost a lot of weight and I got really scrawny, but I was told I had to put on a size for Transformers because Michael doesn’t like skinny girls”.

And it looks as though she’s taking the advice very seriously:

“I eat red velvet cake before I go to bed every night. If you eat meals later, you’ll put on weight faster, so I had dinner at 10pm”.

And as for the movie, which Shia LeBeouf and Megan will star in again, Fox adds

“There are no big love scenes. At this point Shi and I have been dating for two years so we’re at the bickering stage, like an old married couple.”
