Ever think that one celebrity looks just like that other celebrity? We see it all the time and so does the rest of the internet. There's no shortage of sites out there that are dedicated to celebrity lookalikes. But we decided to take it a step further to see just how much certain celebrities look like one another. That can only mean one thing -- celebrity face swapping!

That's right, we took some celebrity lookalikes and decided to face swap them in an experiment that's part "If They Mated" and part "Totally Looks Like." The results are either uncanny, or really, really bizarre. Or both! Check out the weird results below.
