Everyone is saying the same thing about Princess Charlotte today as a new photograph has been released to mark her 11th birthday. Kensington Palace has shared a new picture of Charlotte, taken by Matt Porteous, on the family's recent Easter holiday in Cornwall.

In the photograph, Charlotte can be seen in a garden wearing a black and red striped jumper and jeans. The princess has her long hair down in a casual style as she beams at the camera.

The caption of the photograph read: "Wishing Charlotte a very happy 11th birthday!"

Royal fans have rushed to comment on the new photograph on Instagram, with many pointing out the same thing - just how grown up Prince William and Princess Catherine's only daughter looks.

One fan wrote: She's so grown up looking. I remember the first time we saw her on the steps on the Lindo Wing swaddled in her mother's arms. Time flies."

Another said: "She is so grown up and she is such a gorgeous little girl. Hope she is having a great day."

Someone else wrote: "She's grown up so fast."

Another fan commented: "Happy birthday, you are growing up so fast."

The princess is likely to be celebrating her special day with family.

She was last seen on the royal stage in April attending the Easter Sunday service in Windsor with her royal relatives.
