Jamie looks very familiar to me and I'm pretty sure she's Brandi from Matt's Models http://peachyforum.com/forums/p/222302/679647.aspx#679647
I guess no one else has noticed since she isn't very popular and hasn't done anything new in 5 years but anyway I found this interview for her on UGO http://www.ugo.com/girls/foxyfans-sexy-halloween-costumes-jamie
