Riley, 30, shared an emotional video on Instagram in which she asked her detractors why they care so much about her being overweight.
"You know, there are just some things that my sober mind keeps me from sharing. That ends tonight. I've got some things I need to get off my chest.
"Why does me being fat offend so many people? Is it because I'm confident and I'm fly and I'm sexy? Do my thighs offend? Does my stomach offend? Why?! Why?!"
