Prince William and Kate Middleton have picked a wedding cake flavor ... and it's fruitcake! Sources are reporting the couple have chosen to serve fruitcake to their guests, who will include everyone from stuffy English royals to the ultimate sexy, fashionable couple, Posh and Becks.

William & Kate's Wedding Fruitcake

Although most Americans think fruitcake should only be eaten by force at your weird aunt's house during the holidays, fruitcake is actually a traditional British wedding staple.

It's also a British tradition to save the top layer of the wedding cake so it can be served at the christening of the couple's first child.
