I checked the Kristina Rose links and all I found was massive amounts of video links and lots of hardcore galleries. If I could find this picture in one of the galleries, then I'd be sure it's her.
As for the other ID (Alejandra Maglietti), checked it out and I **** to say it but the girl doesn't match. To make matters worst, there is only 2 links in her gallery and the girl in there is very Hispanic.
