Supposedly M.I.A. signed a contract with NFL for her halftime performance inwhich M.I.A. agreed to indemnify the NFL for any amount of money it might be forced to pay if the FCC decided to come down on NBC.
(If you remember the Janet Jackson wardrobe malfunction during the Super Bowl halftime show, CBS got a $550,000 FCC fine which was dismissed in court).
Sources tell TMZ that NFL does not want to pay the fine and they want to send the message that they do not tolerate M.I.A.'s actions.
