UPDATE (3/1/16, 12:01 p.m. ET): In another Instagram caption, Lena clarified the issue she has with the image.

Hey Tentaciones- thank you for sending the uncropped image (note to the confused: not unretouched, uncropped!) and for being so good natured about my request for accuracy. I understand that a whole bunch of people approved this photo before it got to you- and why wouldn't they? I look great. But it's a weird feeling to see a photo and not know if it's your own body anymore (and I'm pretty sure that will never be my thigh width but I honestly can't tell what's been slimmed and what hasn't.) I'm not blaming anyone (y'know, except society at large.) I have a long and complicated history with retouching. I wanna live in this wild world and play the game and get my work seen, and I also want to be honest about who I am and what I stand for. Maybe it's turning 30. Maybe it's seeing my candidate of choice get bashed as much for having a normal woman's body as she is for her policies. Maybe it's getting sick and realizing ALL that matters is that this body work, not that it be milky white and slim. But I want something different now. Thanks for helping me figure that out and sorry to make you the problem, you cool Spanish magazine you. Time to get to the bottom of this in a bigger way. Time to walk the talk. With endless love, Lena PS I'd love the Tentaciones subscription I was offered!

Lena Dunham is no stranger to covering magazines, nor is she a stranger to championing body positivity. So when a Spanish magazine got heavy-handed with the Photoshop on a recent cover, she took to Instagram to call it out.

Though Lena didn't pose for the cover, the magazine used a shot from photographer Ruven Afanador, but altered the original image and, well, Lena noticed. She writes in the caption: "Oh hello El Pais! I am genuinely honored to be on your cover and so happy you licensed a pic by @ruvenafanador, who always makes me feel gorgeous. BUT this is NOT what my body has ever looked like or will ever look like- the magazine has done more than the average photoshop. So if you're into what I do, why not be honest with your readers? Much love, Lena."

Lena isn't the first cover star to call out a magazine for going way too far with Photoshop — Zendaya recently shared an unretouched photo from her Modeliste cover after the magazine significantly slimmed down her hips and torso.

While it sucks that magazines feel the need alter their cover stars from the way they are, at least we have people like Lena and Zendaya calling them out when they go too far.
