We've seen some great magazine covers and fashion ads in the month of April, but we've also seen some great covers and ads ruined by bad Photoshop fails.

From thinning celebrity waists to adding extra limbs in retail circulars, it seems like obviously bad Photoshop fails popped up all over the place this month.

As this month comes to an end, we pay honor to some of the worst Photoshopping fails we've seen this April 2012.

Click through our slideshow and see just how out of hand it got!

Kim K's newest OPI nail polish ad has us a bit perplexed. While we know Kim has great curves, she has a little too perfect hourglass shape in this photo. We suspect her waist has been thinned or her head has been put on someone else's body.
