AMERICAN actress Megan Fox deliberately put on weight – just to impress her director in the new Transformers movie. The 22-year-old star was keen to make a good impression on director Michael Bay. “Mike doesn't like really skinny actresses,” she said. “He's been unhappy with them for some reason in the past. I was the fattest I've ever been when making a Transformers movie.” Transformers: Revenge of the Fallen will be released this summer.
