The latest app to go viral on Snapchat is giving us the heebie-jeebies; face-swapping has exploded on the social media platform and celebrities have jumped on the techno trend. These freaky images take only a moment to create, but far longer to erase from your mind. Like botched plastic-surgery nightmares, the ill-fitting features of friends and couples are doctored to ghoulish effect. Scott Disick and Kourtney Kardashian, each gorgeous individuals in reality, don’t ‘face-graft’ well at all; altered Ryan Seacrest and Demi Lovato look like a pair you wouldn’t want to bump into in a dark alley, but that would be preferable to seeing them in broad daylight, and not even cuties Chrissy Teigen and John Legend can pull off this look off. The only duo who haven’t mentally scarred us is the Hough siblings – Julianne and Derek’s DNA is so close they could be twins.
