Someone could obviously not keep his curiosity under control while Kate was walking down the aisle, but more than look round, Prince Harry said something to his brother William...
"Wait until you see what she's got on."
That made me laugh.
I admire William for not looking round at all at that point.
Prince Harry, there are people who can lip read in this world, but fun must be had by all, including you and your brother. And admittedly, she really did look stunning, sorry, still looks stunning at this moment.
