On the Millard / Bosma thread, it's been mentioned that LB resembles a model on a *advertiser censored* site who was photographed by Dellen Millard in 2005 at a Millard Air plane hangar. Her pseudonym on the *advertiser censored* site is "Josie". (I believe another poster will be posting comparisons photos here. EDIT: I see they have been posted.)
Having looked at the comparison head shots, I think it's the same person. If it is, and her age is listed correctly in this thread, she would have been under 18 when the photos were taken. I'm kind of torn on this--I won't be surprised if her photo shoot disappears from the site soon, but I can't well recommend anyone screenshot/save it, because if she was under 18 at the shoot, wouldn't possession of the images be illegal?
That *advertiser censored* site has been around a long time, it's a commercial venture, but I don't know how thoroughly they vet the models.
Edited to add: I mentioned in the other thread, but the reason I think it's the same person is not just the overall similarity, but other details like the part of the hair, the nasolabial folds (the lines from her nose under her cheeks), what looks to be similar eye color, etc.
