Did you spot Kate Middleton's nod to Princess Diana in the Cambridges' sweet anniversary video?

The Cambridges are undoubtedly one of the most talked-about families in the world, with Prince William and Kate Middleton never failing to make news.

From Kate Middleton's handy face mask trick to the news that the Duke and Duchess are hiring an important new role for their team, the Cambridge couple make non-stop headlines, especially since their relocation to Kensington Palace.

This past week however, it was the Duke and Duchess of Cambridge's marriage that got the world talking as they celebrated their 10-year anniversary.

Marking the day, Prince William and Kate Middleton posted a heartwarming home video of their family.

Holding hands on the beach, laughing and toasting marshmallows - it's all there - and unsurprisingly, it's going viral.

Eagle-eyed fans were quick to spot a sweet nod to Princess Diana in the viral video, with Kate wearing a pie-crust collared shirt under her red jumper - a look made famous by Princess Diana in the 1980s.

'Thank you to everyone for the kind messages on our wedding anniversary,' the Duke and Duchess of Cambridge captioned the sweet video. 'We are enormously grateful for the 10 years of support we have received in our lives as a family. W & C'

Well, this is lovely.
