Prince William and Kate Middleton's adorable four-year-old son made himself impossible to miss, delighting royal watchers with an array of expressive and very funny faces as the spotlight shone on him during his big balcony moment.
And although Prince Harry wasn't on the balcony to share the spotlight - being no longer an official and active representative of the family - fans couldn't help but think of him, casting their mind back to the years he too thrilled onlookers with funny faces when he was little Louis' age.
