The Duke and Duchess of Cambridge’s rare display of public affection

WE’RE used to it from Prince Harry and Meghan, but this time, it was Prince William and Kate Middleton caught in a very rare PDA.

PRINCE William and Kate Middleton aren’t immune to the romance that surrounds a wedding day.

The Duke and Duchess of Cambridge were caught in a very rare display of affection inside St George’s Chapel, while waiting for his cousin Princess Eugenie to arrive at her royal wedding.

It’s the kind of behaviour we’re used to seeing from newlyweds Prince Harry and Meghan Markle - but William and Kate usually keep their loving displays behind closed doors.

But not today.

The kids are tied up in the royal bridal party - so Mum and Dad are getting wild.

Earlier, the high-profile pair had hurried into the venue with the Duke and Duchess of Sussex, clearly hoping to avoid stealing focus from the bride and groom.

Meghan wore a navy Givenchy ensemble - the same fashion house she chose for her own royal wedding in May - while Prince Harry looked dapper in a morning suit.

Just a few moments later, the Duke and Duchess of Cambridge offered us another blink-and-you’ll-miss-it arrival, stepping out of their chauffeured car and walking briskly into the church.

In an interesting coincidence, Kate also wore a dress by the same label behind her 2011 wedding gown - Alexander McQueen.

The bright pink ensemble and matching hat was a break from Kate’s recent trend of recycling outfits for weddings.
