Queen & Royal Family Celebrate Easter At Windsor Castle! (PHOTOS)

Clad in a festive purple hat, Queen Elizabeth II, along with members of the royal family, celebrated Easter on Sunday with a traditional service at Windsor Castle.

Her Majesty greeted children and sang hymns in a pastel Stewart Parvin silk dress with a lilac crepe coat and a matching hat by Philip Somerville, according to the Telegraph.

Also in attendance and out enjoying the sunny weather: Princess Eugenie in a tan coat and black fascinator, Princess Anne and her husband Tim Laurence, Prince Andrew and Prince Edward with his wife Sophie, Countess of Wessex.

We're just a little sore about one thing: where are the Duke and Duchess of Cambridge? Still on their ski vaycay?

When we last saw the royals, they were honoring a memorial service for the late Queen Mother -- also sans Will and Kate.

Check out photos of the royal festivities below -- happy holidays!
