UPDATE: A source tells E! News that "Sports Illustrated wrote the legal letter [and] Kate Upton has nothing to do with it." A spokesperson for the magazine confirmed to E! News a letter was sent to Celeb Jihad, adding, "We've asked them to take down the photos and will move forward accordingly."
A lot of people would like to see Kate Upton in the buff, but most will have to settle for seeing the 21-year-old Sports Illustrated swimsuit model in a bikini.
Celeb Jihad, however, took the liberty of Photoshopping naked pictures of Upton, claiming the doctored images were "outtakes" from her 2014 swimsuit shoot. Per TMZ, Upton is threatening to sue the site over the fake X-rated images. Celeb Jihad, the self-described "holy Islamic extremist celebrity gossip website," called the purported lawsuit "laughable."
