I think Prejean herself has said the video was her...googled and found this: http://today.msnbc.msn.com/id/33823079/ ... 6Hx1tU2e6U
She says it's not a sex vid...because she was alone...ummmm...ok.
so, I'd say it's likely her. Unless someone knows of another vid linked to her.
Carrie Prejean admits the existence of the tapes but no one has ever been able to confirm they were ever put on line. Here's what we do know. There were at least 8 different videos of her having "solo non-sex with herself" (as she calls it) and at least two sources were known to have had them.
1) The Miss America Pagent people showed the videos to her and her lawyers at a meeting in order to get her to drop her $1 Million lawsuit against the pagent (which she did).
2) Vivid Entertainment had them and wanted to market them but wasn't going to do it (or couldn't do it) without her consent, which wasn't going to happen.
Neither of these sources is likely to leak them on the internet because they have nothing to gain from doing that. To me that's kind of a strike against it's authenticity, but I don't know if it really means very much. Other people had to have them as well. Someone gave the tapes to the pagent and to Vivid and it damn sure wasn't Carrie!
It's possible an exboyfriend put them on line, and Carrie has confirmed that she made them for an ex, but I don't think anyone has ever mentioned the source of the leak or that they were ever put on the internet. She also claims she was 17 at the time, but she had to be at least 18 in some of the videos because there's no way Vivid would have been looking to market them otherwise.
I don't see any reason to believe it is her, but I don't see any reason to believe it isn't either. If it is her, she played it right. Just ignore it, make no comment, and no one will ever know. Some of these celebs involved in hackings and other leaks of compromising material should take note. Freaking out and saying "OMG I'm naked on the internet, please don't look at it" is about the worst thing you can do and only ensures you'll get maximum attention and exposure (like ScarJo, Hudgens, Erin Andrews, etc).
