Lauren is a real model, and her mother seems to not allow any modeling in swimwear and stuff like that and she dosn't post private posts in such outfits (She is posting on VK, Facebook, Instagram, aso.). Maby she want to dodge any problems with overprotecting motheres or the public (See Kristina Pimenova for example).
Lauren is half korean and half canadian, she seems to model since she was 2 years.
There are a bunch of nice pictures of her, but not in high resolution - it's really a pain to see just those stamps-pictures of such a cute girl.
Here are some of the pictures I got.
