She may have been voted the sexiest woman in the world, but the director of Transformers thought Megan Fox was too skinny.

She told Fox News that she was ordered to gain 10 lbs. for the movie's sequel.

She added that she and co-star Shia LaBeouf don't get it on in the blockbuster sequel (which stops shooting in October).

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

"We are super close right now," she told Usmagazine.com. "It's odd that they decided to make [split rumors] up now.

"I guess Im boring," Fox added. "There's nothing else to write about me because I don't go to clubs or do drugs or fall out of cars drunk."
