The "Glee" star went on a painkiller-induced rant on Instagram after undergoing dental surgery -- and she didn't hold back when it came to body-shamers who've been commenting about her weight.
"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 of my chest," the actress said in the clip below. "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? Does my big juicy ass, offend? Why? Why!?"
"Let my big ass live! I let y'all live! I love all colors, shapes and sizes," she continued. "So, just so you know, when you come on here, and you call me fat, it's not an insult, dummy. My ass is fat. And the fellas love it. And so do I. So eat it."

Riley's fans flocked to her defense, writing positive reactions to her comments.
"All that matters is that you are comfortable with yourself. As long as you love yourself then it doesn't matter what anyone else thinks," one wrote. "Ur the best Amber," another added.
Riley's "Glee" costar, Naya Rivera, even chimed in, writing, "Get it giiiirrrrlll."
After Amber got some rest, she returned to the social media site with another message.
"I feel so much better today, I think it's my uncanny ability to laugh at myself and not take myself so seriously. OR maybe it's just my superhero tshirt," she said. "Everyone else is serious enough for me, I'm gonna enjoy life and you should too! Hope u had a fantastical day guys."
We love that she spoke her mind, do you?! Sound off below!
