Megan Fox had to gain weight for her next film – after her director deemed her too skinny.

“I had to put on size for Transformers II because [director] Michael [Bay] doesn’t like skinny girls,” Fox, 22, said. “I had three weeks to gain weight, and I put on 10 lbs.”

The actress, who said she got “really scrawny” for her role in the upcoming zombie film Jennifer’s Body, indulged in some of her favorite foods to gain back her curves: “You know Doughboys?” she asked of the trendy Hollywood eatery. “They make that red velvet cake. I seriously have that every night before I go to bed.”

“I don’t really eat that healthy,” added the actress, who talked to reporters at FOX’s Television Critics Association party July 14 (she attended with boyfriend Brian Austin Green, who stars in Terminator: The Sarah Connor Chronicles). “I have a really bad sugar tooth.”

Megan Fox is still one of the slimmest starlets in Tinseltown, but the uber-sexy 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 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.”

When Michael Bay got behind the camera for his most recent film, he chronicled a lot more than just automobiles transforming into robots from outer space. Millions of fans also watched then 21-year-old Megan Fox transform from an obscure actress best remembered for a Lindsay Lohan movie into one of the most desired hotties on the planet.

Now, the Transformers star is back on the set with Michael Bay – and true to the director’s favorite word, she says he’s making an awesome sequel.

“As big as the first movie was, this is 10 times as big, 10 times as many set pieces, explosions, and acrobatic stunts,” she told us about Transformers: Revenge of the Fallen. “Shia and I make out a little bit; I don’t know if anyone wants to see that.”

Something tells us that Shia LeBeouf wants to see it.
