Prince William and Kate Middleton just passed a huge relationship milestone

Congratulations are definitely in order!

The Cambridges are one of the most talked-about families in the world, but while the Duke and Duchess of Cambridge spend the most time in front of the cameras, it’s their children that really steal the limelight.

From Prince George’s cheeky grin and Princess Charlotte’s sassy comebacks to Prince Louis’ royal wave, these toddlers never fail to make news and this summer has been no exception.

But it wasn’t Princess Charlotte’s first day at school last week that got everyone today. Instead, it was her parents, Prince William and Kate Middleton, as it was revealed that they had passed a huge milestone together.

But what is the milestone in question? The Duke and Duchess of Cambridge have reached 10 million followers on their Kensington Royal Instagram.

These two - such millennials!

The royal couple, alongside the Duke and Duchess of Sussex, paves the way in social media for the royal family, known for their love of emojis and sweet throwback snaps.

It’s hardly surprising therefore that the account has grown as much as it has.

The Duke and Duchess of Sussex have 9.4 million followers on Instagram currently, but given that they only set up their account in April, we have no doubt that they will catch up.

Congratulations to the Duke and Duchess of Cambridge.
