Dumbledore is SO gay. No, seriously. Apparently, JK Rowling has outed him as gay, according to this article (WARNING, it contains some spoilers for the seventh book, but nothing especially major to the plot): http://www.the-leaky-cauldron.org/2007/10/20/j-k-rowling-at-carnegie-hal...
And here is an excerpt from the Dan Radcliffe article below:
Asked who would be his leading lady if he [Dan] played Bond he joked: "Rupert (Grint).
"I'm going to be the first gay James Bond and I want Rupert to be my first leading lady."
"I'm joking," he added.
This is AWESOME!! *cheers* Let's throw a fabulously gay Harry Potter party! We can all put on pink wizard hats and dance to wizard rock! Who's with me? :D
