 The photo has been retweeted more than 18,000 times 
 
 (CNN) When Kaylan Mahomes posted a recent car selfie with her twin, Kyla, and their mother, the social media world went into confusion. 
 
 The caption by the high schooler read, "Mom, twin and me." 
 
 But because all three share the same youthful glow -- it looks more like a picture of triplets -- everyone was trying to figure out which one is the mom. 
 
 Since it was posted January 28 the photo has been retweeted more than 18,000 times and received more than 29,000 likes. Some Twitter users have shared it along with the hashtag #blackdontcrack, an expression that refers to African-Americans whose smooth skin makes them look younger than their age. 
 
 After seeing how much success their selfie garnered, the family created an Instagram page to share more images of the trio, who live in Indianapolis.

– What started out as a simple car selfie has turned into a viral sensation. Kaylan Mahomes of Indianapolis posted a pic on Twitter on Jan. 28 of herself, her twin sister Kyla, and their mom, captioned "Mom, twin & me," CNN reports. But that photo has caused thousands of double-takes, because it's almost impossible to tell the mother apart from her doppelganger daughters. The pic is "causing lots of confusion and also prompting discussion about age-defying products," as the Springfield News-Sun puts it. The photo has already received more than 30,000 likes and almost 19,400 retweets as the world tries to pinpoint who gave birth to whom. And the News-Sun documents viewers' intricate sleuthing methodology, with some Internet detectives insisting the mom has to be in the middle because the two on the outside look too much alike. Others go even deeper: The girl on the right is the one taking the photo, and a mother wouldn't be sitting in the back, so Mom has to be the one on the left in the black blazer. Turns out that last theory is the correct one, though at least one user is content to just be enamored with all three. "I don't understand how so much perfection can be allowed in one picture," the commenter tweets. A video posted on Instagram gives viewers a second perspective on the mom and her two high schoolers. (This dad accidentally took a selfie video in Vegas—and his son uploaded it for the world to see.)
