American fitness model who has amassed over 16 million followers on Instagram. She said on her twitter "I'm actually 5'7 and weigh 140 pounds lol ❤"

I'm sometimes Five-Six, sometimes Five-Seven. I like to say Five-Seven, but then I go to the Doctor and they're like, 'No, you're Five-Six.' Then they're like, 'No, you're Five-Five'....they can't make up their minds, so I'm deciding and I say that I'm Five-Seven.
