Question: What's creepier than a combination of President Barack Obama and Nicki Minaj's faces? Or Julia Roberts and Ryan Seacrest? Answer: Nothing. Someone on the Internet went through the trouble of producing celebrity face mashup GIFs that are truly frightening. 

Disclaimer: You probably won't be able to sleep after seeing the John Mayer + Katy Perry combo face in action. And how about the purdy mouth on One Direction's Harry Styles after he gets Taylor Swift's lips planted (literally) on his face?

Make sure you scroll through the gallery below to see the hideous amazing GIFs.
