There's more to being a model than standing around all dead-eyed in a procession of impractically gaudy outfits while a European man with an unpronounceable name shouts a series of inanely useless instructions at you, you know.

Because it's a little-known fact that to be a model you also have to have several first-class degrees from the world's finest universities in everything from logical empiricism to advanced economic studies otherwise it doesn't count.

Luckily Gisele Bundchen has all of these qualifications and is therefore eminently capable of delivering sweeping statements about the condition of the world's currency markets whenever she feels like it. And that's what Gisele has done – she doesn't want to be paid in dollars ever again, partly over fears of its stability and partly because she probably overheard a bloody fashion designer's assistant say that coins are so last season and that seashells will be the must-have denomination once.
