Honey Ross posed completely nude with Lena Dunham as she paid tribute to the star in a body-positive post.
The star, who is Jonathan Ross' daughter, got naked to pose for a cheek-to-cheek post with the Girls star.
The 24-year-old thanked Lena for helping her "shape her relationship with herself".
"I’ll never be able to fully express how much this woman shaped my relationship with myself, but I’m going to do my best to try," she began.
"My mum bought me the DVD of Tiny Furniture when I was a very self-loathing chubby teen, and I saw Lena’s beautiful face on the cover, and I felt hope.
"A new hope that I’d never felt before. I watched the film and was so moved by its rawness, by the way it approached sex, friendship and figuring out that liminal space before you’ve got your shit together."
In the snap, Lena and Honey were on their knees as they sat next to each other on a hotel bed.
Honey added: "And I wept because I’d never seen someone who looked like me - a beautiful chubby Jewish girl - be the star of the show. And not just the star – the writer, the director and the lead.
"When Girls came out a couple of years later, I gained a new confidence in my walk. Lena was the main character, and maybe I could be too. I saw myself as a viable love interest for the first time."
"I saw myself capable of a life beyond being just a ‘before’ photo," she said. "Seeing Lena’s beauty and talent on screen helped me learn to see those things in myself. I’m so grateful for this woman, for the stories she continues to tell.
"And meeting her for the first time, all these years later, proved to me that everything they say about meeting your heroes isn’t always true. And the second time we met, we took the photo you see above."
She went on to tell fans that the "full story" can be heard on her podcast, which Lena took part in.
"She is, and will always be, a woman who holds an incredibly special place in my heart. We also both have identical bodies and the same specific kind of arthritis so if that ain’t special, I don’t know what is," the writer concluded.
Fans took to the post to praise the two stars for showcasing "real women".
Honey also shared a few quotes from Lena, which is all part of Honey's The Body Protest.
"It's interesting because as I get older, I realise there are a lot of deeper struggles than being a chubby girl in a world of skinny people, but that was my struggle and it definitely formed me," a quote from Lena read.
