You guys who think a 5'6" 170 lb. woman has to be fat have NO idea what you're talking about. Habitual health posts here occasionally, and those are about her stats (she said in her photo shoot she was 5'7" and 169)

A 6'3" 170 pound woman is skinny fat territory, you're talking supermodel proportions. She can't possibly have any muscle on her, though, just not possible.
Stop judging what's potentially hotness by a scale, will you please. Go by what pleases the eye, hell, go by frigging calliper and BF measurements if you must, but stop placing value based on scale numbers. Most women, particularly those in the entertainment or fashion industry, either lie like shit about what they weigh, or they are at an extremely unhealthfully low bodyweight for their height, maintained by starvation and nothing else. Looks good on camera, after makeup, wardrobe and photoshopping, but in reality, ick.
