Oh hai Jedi Knight Princess Leia!

That is not fan art, in Star Wars' Expanded Universe (novels, comics, games, other things considered canon) Leia eventually decides to become a Jedi. Now if only women would start cosplaying as this instead of Slave Leia. I think the latter is overdone and imagine how awesome it would be to see Jedi Knight Leias walking around Comic-Con instead of a legion of ten thousand women in the same gold bikinis that you see everywhere.
