Prince William and Kate Middleton‘s royal wedding was one of the most celebrated events of the decade – and watched by nearly two billion people across the globe.

On April 29, 2011, the university sweethearts said ‘I Do’ in a fairytale ceremony held at Westminster Abbey before walking out to the sound of cheers from thousands of well-wishers who had lined the streets of London.

Yet while the pressure of marrying Britain’s future King may have seemed daunting to some, Kate was an ‘unflappable’ bride who had ‘no tearful scenes, no last-minute panics’ and ‘no tantrums,’ according to royal author Tina Brown.

After exchanging vows in front of almost 2,000 guests, the newlyweds prepared to climb into their carriage and travel towards Buckingham Palace, with footage capturing some of their first words as a married couple.

According to lip reader Nicola Hickling, their candid conversation revealed intimate details about how they were feeling on their big day, and the prince’s desire to reassure his bride.

Speaking to the Daily Mail, Ms Hickling revealed that William was keen to check in with his new wife as soon as they found a brief moment alone and asked: ‘Did you enjoy the ceremony?’, to which Kate flashed a smile and replied: ‘Yes.’

Dressed in the tunic uniform of the Colonel of the Irish Guards, William was seen putting on his white gloves and added: ‘One second, then I’ll jump straight on [referring to the carriage].’

A glamorous Kate, who donned an elegant £250,000 Alexander McQueen gown, responded: ‘Okay’. William, ever the gentleman, then swiftly added: ‘I’m quite glad you felt comfortable, you go first.’

Once the couple had settled into the 1902 State Landau carriage in preparation to travel down The Mall, William asked Kate if she was ‘comfy’, before the new princess turned to him and asked: ‘Are you happy?’

‘I am to be fair,’ said William. ‘You look wonderful,’ he complimented his blushing bride.
