With Kate’s stunning Alexander McQueen gown, the lavish background of London’s Westminster Abbey and an endless number of A-list guests, the Duke and Duchess of Cambridge’s wedding feels like it was just yesterday.

However, it’s actually been more than a decade since the world watched Kate Middleton walk down the aisle to marry her university sweetheart Prince William in 2011.

As Kate, 40, made her way through the well-wishers alongside her father Michael Middleton, William pushed back the nerves as he grinned from ear to ear.

But when cameras panned onto the happy couple, the Duke of Cambridge could be seen whispering a few words to his wife-to-be before uttering something to Michael, too.
