Actual Celebrities Are Using POPSUGAR's Celebrity Twin App Now, and Oh My Gosh

Sure, people might tell you you're a dead ringer for a certain celebrity, but how can you really be sure? Well, there's a tool for that! Last year, POPSUGAR launched #Twinning, a website that presents users with their celebrity doppelgängers . . . to varying degrees of success, admittedly. You probably even saw several celebrities sharing their results in recent weeks. (For the most part, they got matched with themselves.) It's not quite a game, not quite a meme, but you'll definitely want to share the results. Some of them are perfect; some look nothing like you — and that's the fun of it.

It's simple: #Twinning analyzes a selfie or uploaded photo, then compares it to a massive database of celebrity photos to find matches, and finally gives you a "twinning percentage" for your top five look-alikes.

The tool itself is pretty simple: it analyzes a selfie or uploaded photo, compares it to a massive database of celebrity photos to find matches, and gives you a "twinning percentage" for your top five look-alikes. You might pair with a famous politician, an old-school Hollywood starlet, or a reality TV personality, and the results will vary based on which photo you upload! Now, fair warning that your matches might bring up some fairly existential feelings: do I really look like my mom's favorite '90s soap star? You're a 35-year-old woman — how on earth is Jacob Tremblay your match? Hey, it happens.

Check out some of POPSUGAR's very own matches ahead, as well as a few celebrity matches, then prepare to be hooked when you try the free tool for yourself. Let us know your doppelgänger(s), whether they're spot-on or hilariously wrong — it's all in good fun!
