And I can't see why not. She's always been athletic, she must have done a lot of sports, there's no reason for her not to appreciate an athletic figure. Besides, why would she lie?
Well, she eulogised about how great it was to be buff, and wanting to set a great example, but then lost a huge amount of muscle. It seems that she regained a little for her newest film, but I saw photos of her last year looking very stringy and typically Hollywood-thin, which suggested to me that she wasn't as enamoured with being buff as she said she was. And as to lying - it's Hollywood - LaLa Land - people will say any amount of bull to position themselves.
