The Andrew Bynum one was definitley real, it was made far before he was big, and if you look through his friends, all of them were from the same town, and they all made comments that made you think they knew him personally. Plus, the fact that it got taken down the day after he was drafted also proved its authenticity. It means the PR guy on the Lakers said you look like an idiot, take this down, and he did.
The Horry one is probably not real, and same thing with the rest of them. But, you never know, Britney Spears has a Xanga.
