I don't think Beyonce cares as much as we do. You guys HAVE to understand, Beyonce has been in the game for OVER 15 years. There has been FAR worst things that have happened to her (DC split and them calling her a bitch, Pregnancy situation, the huge backlash at the beginning of the B'Day era), and she ALWAYS managed to come back on top.
I think she is just used to it.
