Prince William, Princess Kate and Prince Harry Get in the Christmas Spirit at Youth Center

The royals attended a Christmas party at a youth center.

William, 34, shared with DJ AJ King at the event that William and Kate's son, Prince George, 3, is so excited about Christmas that he has been unwrapping presents under the Christmas tree.

"The Duke said they were all really excited about Christmas and that George is already opening his presents," DJ AJ King said. "He thought it was quite funny. That's kids for you, even the ones that are princes."

Kate participated in icing a gingerbread house at the party, while also joining William and Harry, 32, in making Christmas decorations.

The royal trio presented the award for The Mix's volunteer of the year. They also heard from staff members who participate in online and telephone counseling at The Mix.
