'Does she age?' Incredibly youthful-looking 40-year-old woman goes viral with her before and after picture of herself and her teen daughters (Details, pics)

A youthful mom is causing internet users to do a double take after a now-and-then photo comparison of her and her daughters was shared online.

Kienya Booker, 40, of Nova Scotia has gone viral thanks to the images, which show off her age-defying good looks.

It began when Kienya shared a collage of images showing herself with her girls when they were just young children and what they look like now.

The mom-of-three, who has more than 79,000 followers on Instagram for her natural hair tutorials, even just looks like the oldest of three sisters in the first photo with her daughters K’Lienya, 18, and Kolieya, 16, Smith.

The girls are regular features on Kienya's Instagram page, sometimes posing as models for their mother's various expertly styled looks.

Speaking to Yahoo Lifestyle, Kienya explained that the photos started as just a regular throwback Thursday post.'

The top half of the picture was a throwback of me and my daughters from about 12 to 13 years ago, and the bottom half was a more recent picture of us,' she said. 'Soon enough, other users were taking the photos from her page and turning them into memes - with all along similar lines. And that’s when it all started.'

'She’s not the mom, she’s their sister' said some users, while others added: 'Did their mom even age?'But not all the comments were so flattering, with some accusing Kienya as simply posing as the girls' mother for attention.

Others suggested that she must have had the kids when she was 15 years old in order to look that young - which is obviously not the case.

As for the experience as a whole, Kienya claims she was a 'bit thrown off with some of the negative comments,' but has otherwise loved the reaction to her photos, and has happily shared some of the more positive coverage that her ageless appearance has received.

The mom has shared a number of other photos of herself with her girls, showing that the original image was no fluke as it's always nearly impossible to tell which is the mom.

However as far as the mystery about whether or not she really does age, her husband OBryan cleared that up when he posted a happy birthday message to his wife of five years on his own Instagram account - although he graciously left out her actual age.'

'Happy Birthday to my beautiful wife @kienyabooker,' he wrote. 'I [love] you very much! I thank God for you and that you were blessed to be here another year! Fine Wine or China ain’t got nothing on you!!'
