Ariel Winter looks like a new woman!

The Modern Family star posted pix from a friend's party and showed off a shockingly-slender new look! We think she looks amazing (and she looked amazing before, too), but some fans didn't like Ariel's skinnier frame.

"Omg you lost your butt!" one commenter wrote. Another: "I’m sorry you felt the need to so dramatically change your appearance. I liked you just as you were. I hope you are happy in your new body though."

Poor girl can't win! Why is losing weight caving to societal pressure to be skinny ... maybe it's just exercise and healthy eating!

One troll even suggested Winter had plastic surgery to achieve the new look: "Nothing wrong with being honest and telling her we liked her better before ‘the change’ she was so beautiful before she started chopping up her body and if me saying so helps one gurl out here to feel beautiful who’s thinking of PS its worth it."

But Ariel wasn't having it and fought back ... responding: "I appreciate you wanting to help girls love themselves the way they are, but you are also kind of cutting someone (me) down which isn’t what I think you were trying to do?"



She's clearly been putting in time at the gym so we say, more power to you, girl. You look Grrrrreat!
