网民们抓狂了，因为Kaylan Mathomes发了一张在车里的自拍：妈妈、双胞姐姐（妹妹）和我。三个人看起来都一样青春！大家疯狂转发，都在猜到底谁是妈妈？CNN的女支持人咬牙切齿地说：她是用什么面霜啊？这不公平？

你能看出来谁是妈妈吗？答案在英文里找。

这个帖子传遍全球。

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.

But the big question remained: Which young-looking lady is the mom?

In an interview aired Friday on HLN, the trio put speculation to rest by revealing that the twins' mother, Tina, appears to the far left in the photo.

Asked by Christi Paul how she stays so well-preserved with two 16-year-old daughters, Mom broke down her methods.

"I try to drink a lot of water, I try to stay stress free," the 35-year old said. "I just focus a lot on emotional inner beauty."

The family said they're mistaken for triplets "all the time."

"Even people who I know personally still don't know who's the mommy," Kaylan told HLN.

The pic was snapped when Mom was picking the girls up from school; Kaylan shared it with a friend and it went viral quickly thereafter.

Even before the big reveal, the family's second Instagram post offered a crucial clue.
