All too often, us girls like to sit around and curse the cuter, skinnier girls in Hollywood who seems to have gotten their good looks by the grace of God.

But Cameron's here to tell you, ladies, that you've gotta work!

How many times have you see her grace the pages of our blog -- photos of her sweating after her workout, walking to her car with her trainer. That bod doesn't come easy, people!

We applaud you, Cam, on having such a great workout ethic and if it gets you guys like Justin and Paul Sculfor, we should all take note!
