Britney Spears went to a party in the valley last night wearing … I have no idea.  Some kind of tribute to cupcakes and history, I guess.  Please note that no one else is wearing anything pirate related.  And there are no mermaids or nurses, so it's not like it was a theme or early Halloween party.  Britney is the only one who bought her outfit at Six Flags, not to mention the only one whose belt is begging for mercy.
