I think the blonde one is her but that looks like a really old photo to me - I haven't seen her in ages (6+ months or so) but last time I did her arms and legs weren't as thin as in that photo. She's still an attractive girl and one of the best in Brum imho. From the latest blonde samantha review thread they're saying she's now gone brunette, so it is the same girl.
Is that blonde photo from her private gallery? I can't find it on her profile.
