I’ll level with you here: I have no idea what the hell this is. Apparently, BBC Radio 1 got Britney Spears on a green screen and had her read a book while pretending she was flying around on a broomstick, and there’s like a zombie guy and … no, seriously, what the hell? Either way it’s vaguely holiday-appropriate, and in that respect, if I have to celebrate Halloween by choosing between this or Paris Hilton dressing up as Miley Cyrus, I’ll take whatever this is any day of the week.
