13 Hilarious Celebrity Snapchat Face Swaps, Ranked In Order Of Ridiculousness — PHOTOS

Few things on the Internet are as simultaneously terrifying and hilarious as Snapchat face swaps. Thanks to the app's update, it's way easier to switch faces with anyone — from your best friend to your mom to a picture of your favorite celebrity. Way back when, there were sites like Face In Hole that could help you accomplish this, but luckily, Snapchat has made it simpler than ever. So much so, that celebrities love face-swapping. The trend is practically sweeping Hollywood.

From John Legend and Chrissy Teigen to Kylie Jenner and Tyga, some of the most popular celebs have decided to switch looks with their significant others. The results are definitely interesting, to say the least. You'll either have a good laugh or nightmares for a whole week — so proceed with caution, if you decide to read any further. People have even taken the face-swapping trend a step too far by switching places with inanimate objects, like nesting dolls and stuffed animals. Yikes!

Still, it's all meant in good fun. To celebrate, this brilliant technological advance, here's a round-up of the best celebrity face swaps. I've decided to rank them, based on important factors like funniness and scariness.

13. DMX

Sorry, but DMX's face swap comes in last place in this unofficial contest. It's only because he seems so confused by the whole thing. At least he's a good sport when his goddaughter Paige Hurd tries it out.

12. The Houghs

It's scary how much alike these siblings look. Derek Hough says, "It doesn't even look creepy," but I'd beg to differ.

11. Kendall & Kylie Jenner

This doesn't rank higher, simply because there are a ton of Kardashian-Jenners on this list and I'm not all that impressed. It's nothing too out of the ordinary, since Kendall and Kylie almost always do things together.

10. Demi Lovato & Ryan Seacrest

Oy! This face swap between the "Confident" singer and American Idol host is not the most flattering thing I've ever seen.

9. Kourtney & Kim Kardashian

Similar to Kendall and Kylie, Kim and Kourtney look quite similar. I had to spend a solid minute trying to figure out which was which. Will this take off and become the new version of "The Dress"?

8. Kylie Jenner & Tyga

This definitely shows Kylie and Tyga like you've never seen them before. I also never expected to see Kylie with a neck tattoo.

7. Vanessa Hudgens & Selena Gomez

Sure, it's practically impossible to tell Hudgens and Gomez apart here. But they rank this far down the list, since I love that they are still close after filming Spring Breakers together.

6. Ashley Benson & Shay Mitchell

Everybody's favorite Pretty Little Liars pair (aka #ButtahBenzo) decided to swap faces. Ashley Benson looks sorta like a brunette Kate Hudson on the left, meanwhile Shay Mitchell could be a new Kardashian. This one isn't frightening, but they do look like totally different people.

5. Demi Lovato & Nick Jonas

The highlight of this face swap is Lovato saying she looks like Joe Jonas. That's what made this video crack the top-five.

4. John Stamos & Bob Saget

The Full House stars decided to swap faces. As John Stamos says in the video, "I don't like this." I totally agree. I don't like it — I love it. It's hilariously terrible.

3. Kourtney Kardashian & Scott Disick

Isn't this one mind-blowing? Honestly, I don't even think it looks like either of them. It's like two Frankenstein humans, which makes it all the more funny.

2. John Legend & Chrissy Teigen

Ugh, just another reason to love Legend and Teigen! They laugh throughout the entire video. Sure, it's a bit disturbing, but aren't all good face swaps?

1. Kim Kardashian & Kylie Jenner

Kim and Kylie totally win. There may be other pairs of similar-looking siblings on this list (some even belonging to this same family), but these two take first place, since I hadn't previously realized that they're practically doppelgängers. They could easily pull a Parent Trap and switch places.

Wasn't that fun? Admittedly, the ranking skewed more towards the ridiculous options. But that's exactly how face-swapping should be.
