We've all heard of the crazy things musicians want in their dressing rooms when they perform. JLo is rumored to demand only white candles and furniture. Madonna won't go on stage if there isn't a new toilet seat in her dressing room backstage at her concerts. And who can forget the infamous brown M&Ms concert rider in Van Halen's contracts? Well, the NFL has a contract rider of it's own - they want the next Super Bowl halftime performer to pay them to perform!

Super Bowl halftime performers don't usually get paid. The prestige of the gig translates to a payoff in higher tour or album sales for the artist after the big game. This year, however, because the NFL isn't making any money off the big game, they've asked the three finalists for the halftime show - Katy Perry, Rhianna, and Coldplay - to give the league a portion of their post-Super Bowl appearance tour money, or, if they don't want to do that, they can just give the NFL some money upfront.

The NFL makes billions of dollars a year. Asking artists to pay to play is really cheap looking.
