A new family photo of Kate Middleton and Prince William with their children was released Friday on the Twitter account of Kensington Palace. The palace also said early Friday that the 2-year-old Prince George is all ready to go to school before the end of January.

The picture, which will serve as the royal couple’s Christmas card, was taken by photographer Chris Jelf in late October and shows the couple sitting on the grass with their children, along with a small red toy in front of them.

"A new family photo - Merry Christmas from The Duke and Duchess of Cambridge, Prince George and Princess Charlotte. The Duke and Duchess are hugely appreciative of all the warm messages they have received about their family this year and are very much looking forward to their first Christmas as a family of four," the palace said in a post on its Instagram page.

Speaking about the photo session with the royal family, Jelf said, according to Hello! magazine: "I thoroughly enjoyed photographing a very lovely family, although you have to be sharp as you don't have long when there are two young children involved!"

"I hope everyone enjoys this photo and I am honored that the Duke and Duchess have decided to share it with the public," Jelf added.

The palace also announced that Prince George will go to the Westacre Montessori School Nursery in Norfolk from January. The school said, in a statement: "We are looking forward to welcoming George to our nursery where he will get the same special experience as all of our children."
