Nicki Minaj's ESPN cover with Kobe Bryant ESPN

It is no secret that celebrities are regularly retouched and Photoshopped on magazine covers and billboards to make them look as flawless as possible. The latest victim of retouching gone wrong is rapper Nicki Minaj, who is on the latest cover of ESPN's music issue, alongside NBA star Kobe Bryant.

While it is unclear exactly what was done, Minaj’s face look a bit off. Her nose looks different, and her forehead seems to have been elongated. While the cover came out earlier this week, Minaj stayed silent until Thursday. The 31-year-old posted a photo of the cover on Instagram, along with the caption, “When retouching goes wrong.” Within three hours, however, she deleted the photo caption, simply leaving the picture of the cover photo.

Last week, Lena Dunham of “Girls” was on the cover of Vogue and landed in a Photoshop controversy. It is no secret that photos of women are regularly airbrushed in magazines, with their waists and thighs digitally slimmed, their chests amplified, and their skin erased of any imperfections, to the point where some women are practically unrecognizable in the "after" pictures.

But Dunham seems to be a special case, as she often parades her naked body onscreen for her HBO hit series, though she has a rather “normal,” non-model body that is often criticized in the media. She clearly has no qualms about her features, so why should Vogue want to change it, most people wondered. Yet, though she has a body confidence that most women would envy, the elite magazine decided to retouch images of Dunham, which Jezebel documented, showing that they did slight tweaks, such as raising a waistline and slightly narrowing a jaw.

With all the controversy surrounding the retouched images, Dunham decided to respond, writing on Twitter, “Some s--- is just too ridiculous to engage. Let’s use our energy wisely, 2014.”

It is no secret that photos of celebrities are constantly being airbrushed, and a number of them in recent years have come under fire because of it. While Britney Spears has gotten into great shape over the past few months, it seems she's still not perfect enough to escape Photoshop. The latest video from the pop princess, “Work B*tch,” is said to have been retouched, with images being reformatted to make Spears look slimmer and airbrushed to perfection.

HOAX Films recently released unaltered images of the 31-year-old pop star in still shots taken from the music video. The "before" images show Spears with a thicker waist, arms and thighs. When placed next to the digitally enhanced image, reportedly the image used in the final cut, the singer looks noticeably different. The Daily Mail reports that HOAX was supposed to “clean up” the photos.

In 2009, unedited photos of Kim Kardashian for Complex magazine were released, showing cellulite, a larger waist and uneven skin tone. People were quick to point out Kardashian's imperfections. Kardashian addressed the pre-Photoshopped photos, writing on her website, "So what: I have a little cellulite. Yes, I am complex! What curvy girl doesn't?!"
