The former Transformers star showed off her healthy curves in leather shorts in August. Her trainer Harley Pasternak told HollywoodLife.com the actress struggles to put on weight. "Believe it or not she has this really fast metabolism. So her training is all about body toning and sculpting. With her it's really about she's eating enough of the right things. People thought 'Oh she must be anorexic,' but she's far from that!"
