‘Who's the mom?’ biggest internet mystery since 'The Dress’It’s the mother of all internet mysteries.An Indianapolis teen posted a selfie with her twin and her mother on Jan. 28 that has the internet asking, “Which one is the mom?”Kaylan Mahomes uploaded the pic of the three ladies in a car with the caption, “Mom, twin and me,” but the fresh-faced women look identical.The puzzling pic has been retweeted more than 19,000 times and counting, and received more than 31,000 likes - similar to how “the dress” took the web by storm just under a year ago, where readers couldn’t decide whether a washed-out snap of a striped dress was white and gold, or black and blue. The original Dressgate article on Buzzfeed received more than 37 million hits.Some Twitter users are also sharing this new “Who’s the mom?” snap with the hashtag #blackdontcrack, which refers to some African Americans’ age-defying smooth skin.The amused family created an Instagram page to share more photos of the indistinguishable trio after seeing all of the attention they were getting.And their second post gives a clue that could crack the case.The video shows the three ladies posing for a picture while one holds the camera - and then they all start laughing after realizing they are actually being videotaped instead of photographed.The lady on the left, who laughs last, takes the longest to get the joke - and the caption reads, “When your mom thinks it’s a picture...lol.”This lady looks very similar to the woman wearing the blazer on the far left in the first photo.Meet the mom?There’s also the fact that the original photo is captioned, “Mom, twin and me,” which would literally translate that from left to right, the women pictured are the mom, the twin, and the photographer.I picked wrong one.
