I just googled their pictures.

For Paris, it's a Catrina Lopez

For Isabella, it's Stacey Mari

For Monica, she's been discussed before in the past. I recall she had a review, but changed her phone number. She is not GFE, and not sure if the pictures are hers. I didn't check.

As for Julie, those pictures are definitely fake. She was discussed in the DC boards. I was the one the posted a thread about her. Those pictures are of a young model, and that is definitely not her as advertise on BP.

Finally, for Jessica. I think it's her. Those are average pictures. Researched the phone number, and nothing came up. But, out of all the girls, I'd go for this if this is my only option.
