"Oh hello Spanish magazine Tentaciones! I am genuinely honored to be on your cover and so happy you used a pic by @ruvenafanador - he always makes me feel gorgeous," Dunham, 29, told her 2.4 million followers.
"But this is not what my body has ever looked like or will ever look like - mad photoshop has been done to this iteration," she continued. "So if you're into what I do, why not be honest with your readers? Much love, Lena."
Lena Dunham is best known for how comfortable she is in her own skin. She deliberately flaunts her not-exactly-size-2 body onscreen. This confidence, paired with the fact that she speaks so candidly about her body image issues, is what's made her such a prominent leader of the body-positive movement for years now.
On the cover of Tentaciones, the headline even proclaims that she is changing the face of feminism—so why would they change hers?
Well, in an open letter to Dunham, the magazine denied retouching the photo, which it said it had acquired from the Corbis agency.
“We do not use Photoshop nor other digital tools to change the physical appearance of our cover stars, nor in the features to be found inside,” said the letter. “On this occasion, the only thing we did was to crop the image to adapt it to the format of our front page.”
Tendaciones even linked to the original photo that was shared in 2013 by the photographer Ruven Afanador on his Facebook page to show that the images are identical.
So, it's possible that some other party altered the photo before Afanador shared it a few years ago and Dunham never saw the final product until now.
Dunham posted a new photo of the cover after receiving Tentaciones' letter, with this caption:
