Prince William and Kate Middleton feature in Princess Charlotte’s birthday photos – but can you spot them?

earlier today, the Duke and Duchess of Cambridge shared four new snaps of their middle child.

They were taken by budding photographer Kate, 38, and included a new portrait, as well as candid shots of the little girl handling bags of fresh pasta they had made to give away.

A fourth picture showed the back of Charlotte as she knocked on a neighbour's blue door - however she wasn't alone as she waited for someone to answer.

In the reflection of the glass could be spied her mum clutching a camera as well as William, 37 - whose arms and foot appeared to sneak into the background of two of the other photos as well.

The images were popular with royal fans who have left more than 1.5m and 22,000 comments.

One person wrote: "What a wonderful thing to teach a five-year-old to care about others less fortunate. She is adorable!"

Another shared: "Look at her go! It's great to see them involved and have a realistic view of her country."

And a fourth added: "Few five-year old's are given the opportunity to perform a service for the community.

"Good for you for teaching the children that it takes only a little effort to brighten someone else's life."

The pictures were taken by the duchess last month as the family carried out door-to-door rounds taking supplies to those living near their Norfolk country home Anmer Hall on the Sandringham Estate.

Earlier today, Kate and William shared a sweet additional photo of Charlotte holding some of the pasta they delivered.

The Queen also marked her great-granddaughter's birthday with a series of throwback snaps.
