I've seen both girls before, the one taking all the self-shots has been identified in this forum, however after searching back. I couldn't find it. I'll search some of my own posts later and see if I can come up with a name for you. If I remember correctly she purposely ****** her own pics for popularity.
As for the one in red, I have seen her pics, and haven't seen anyone ID her yet, not saying it hasn't happened, but I'm not on here daily like I used to be.
