Biggest celebrity I can think of that I went to school with is probably Jaycen Blair. Infamous bullshitter.
He graduated ahead of me though. Closest thing to a celebrity in my class would have been Lindsay Czarniak, who is assistant to George Michael now, who the locals would know has been doing the local sports since the dawn of time. She was hot back in high school and probably looks even better now. Also my friend Carlos Bonilla is some big shot DJ out in LA now. He's worked with some big name stars before.
I never saw any of them naked.

There are also quite a few car show whores/softcore internet porn stars that have come out of Centreville. Amy Truong a.k.a. Amy Nguyen (XoXoAmy.com-Official Site of Amy Nguyen : Import Model + Girl Next Door) probably being the most well known. She was behind me in school by many years. She was once on FHM's 50 Hot Dates (which is just low caliber models trying to get exposure- none of them are interested in dating you) as were a few other girls who I know around here. Never saw her naked at school, either, though she posts images of her naughty bits on her website now with regularity.
