The not-always-reliable British tabloids say BEYONCÉ is being a total DIVA as she prepares for her Super Bowl halftime performance.

--Among her huge list of demands is this one:  That her daughter Blue Ivy's cedar bed be shipped from New York to the Louisiana Superdome, where it will be placed in a nursery decorated with rose-scented candles.

--That nursery must also be kept at a constant 78 degrees.

--A source says, quote, "She's by far one of the most difficult celebrities we've ever dealt with.  The list is as long as my arm.  She may be a superstar, but this day is about football not her."

--However, an NFL rep calls this, quote, "pure pulp fiction," adding, "Beyoncé and her team have been great to work with throughout this process."
