Prince William and Kate Middleton are less popular than people are led to believe

Prince William and Kate Middleton are considered the most popular royals in the UK.

The Duke and Duchess of Cambridge reached 13 million followers on Instagram on Prince George's eight birthday last year.

They have yet to hit 14 million mark days after Prince George turned nine.

The royal couple is also far from getting one million subscribers on their YouTube channel, which they launched in May last year.
