Megan Forced to gain 10lbs

LOS ANGELES —  Megan Fox is still one of the slimmest starlets in Tinseltown, but the ubersexy screen siren was sporting a few more much-needed curves beneath her “Star Wars” T-shirt and jeans at the FOX Television Critics Association party in Santa Monica, Calif., on Monday night.

Fox was forced to gain 10 pounds in three weeks for her role in the second “Transformers” movie following a dramatic and dangerous weight loss for her last film, “Jennifer’s Body.”

“I should have toned up for ‘Transformers’ but I’m really lazy. I had to put on weight,” she told Pop Tarts. “I’d lost a lot of weight and got really scrawny, but I was told I had to put on size for ‘Transformers’ because Michael [Bay, the director] doesn’t like skinny girls.”

But what dangerous dieting regime did Megan use to pop the pounds in the first place?

“I just stopped eating,” she said. “I don’t eat very healthy anyway — I have a serious sugar tooth, so now I eat red-velvet cake before I go to bed every night, and if you eat meals later, you’ll put on weight faster, so I had dinner at 10 p.m.”

The filming for “Transformers: Revenge of the Fallen” kicked off just last month, and while the 22-year-old was under strict orders not to say too much, it seems like there will be a few disappointed male admirers.

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