Britney Spears is demanding an apology from Maxim Magazine after discovering that the skin mag listed her as one of the Five Unsexiest Women On The Planet.

A mole tells OK! “She started to pout and her eyes were filling up with tears. She had no idea there was such a thing as an Unsexy list and it came as a pretty big shock.”

A source close to singer says, “Brit’s been talking about demanding an apology from Maxim.”
