Princess Charlotte Helps Give Back in Sweet New Birthday Portrait Taken by Mom Kate Middleton

Princess Charlotte has turned 5!

Just in time for her fifth birthday on Saturday, Kate Middleton and Prince William have released a new photo of Charlotte, which was taken by Kate last month.

In the sweet photo, Charlotte is wearing a black-and-white checkered dress with ruffle details around the collar and is also holding a bag of homemade pasta, part of her volunteering efforts with her family amid the coronavirus pandemic.

“Thank you for all your lovely messages on Princess Charlotte’s fifth birthday!” Kensington Palace wrote alongside the photo. “The Duke and Duchess of Cambridge are very pleased to share a new photograph of Princess Charlotte, taken by The Duchess this April.”

The previous day, Kate and William released four additional photos of Charlotte, showing her packing up and delivering food for older residents living near the family's country home, Anmer Hall, in Norfolk, where they've been staying amid the health crisis.
