I really hope that this thread hasn't gone cold, 'cause I just found it, and all of you (except Kouvre) seem to know your shit. I have always had some curiosity about this model, and here is what I think I know: the name Mia Tyler is an alias (maybe having to do with the Aerosmith dynasty), she is Swedish by blood (born in Stockholm) but she is an American citizen living in North Carolina, she was born sometime in 1978, she actually knows something about the law. This is what I have gathered, from very stray, questionable bits.
Please, please, fill in the blanks, correct the incorrect details. I do not keep up with magazines, so if there was ever a penthouse interview, then I wouldn't have seen it. A comprehensive biography would be so unlikely, and so gladly received.
