When Ariel Winter told Kim Kardashian West, 'I gotchu,' she meant it.

The 18-year-old Modern Family star, who came out in support of the reality star after she was criticized for posting a naked selfie, defended Kardashian again on Thursday's Kyle & Jackie O Show.

"I think she's promoting body positivity," Winter said. "Young girls being able to express that they don’t have a stick-thin body, they’re curvy. And stick-thin bodies are amazing and those girls are amazing too. I think that everybody's body should be celebrated, no matter what it is."

"I think that it's great that she's so comfortable with herself and that she's able to post out there what she wants to post. And if she wants to post a nude selfie, she can," the actress added.

Kardashian drew ire from celebrities like Bette Midler and Chloë Grace Moretz when the 35-year-old posted a completely nude selfie earlier this month. Winter later tweeted, “No one was body shaming @justinbieber when he posted his nude guitar photo so why @KimKardashian? #herbodyherchoice"

It's a point Winter reiterated on the Australian radio show.

"There are so many guys that go out there that are so cool for posing nude," she explained. "Then when women do it, we're really crucified. We're not able to do the exact same thing, and I think it's really upsetting to be in an industry where that's happening, so I really decided to stand up for her because I thought it was so ridiculous. It's not hurting anybody at all. If somebody doesn't like the post, they can unfollow her."

Winter has long been a vocal advocate for body positivity, penning a number of Twitter posts and essays about confidence and calling out haters.

“Women are allowed to wear whatever they feel comfortable and confident in, and we should never ever be judged based on appearances,” she wrote. “ALWAYS be confident, and ALWAYS love yourself no matter what anyone else says. I feel so grateful for all the love I have in my life, and I will always work to spread love instead of hate.”

She also opened up to ET about why she's "not ashamed" to show off her breast reduction surgery scars. Find out what she had to say in the video below.
