Girls balance books on their heads to practise deportment during the 'Princess Prep' special workshop called 'Regal Rules: An Introduction to Royal Manners and Behavior' in central London on Saturday, April 2. A scene straight from "My Fair Lady" played out at a posh London hotel Saturday as a dozen girls in frilly dresses attended a "princess boot camp" ahead of this month's royal wedding. The pint-size wannabe princesses learned how to walk straight, eat with decorum and curtsy. Never mind that it's doubtful any of them will come within spitting distance of the royals at the April 29 wedding of Prince William and Kate Middleton.
