Prince William, Prince Harry, Duchess Kate and royal children join the Queen for her annual Christmas lunch

Photos of Prince William, Prince Harry, Duchess Kate Middleton, Prince George and Princess Charlotte traveling to the annual Christmas lunch with the Queen on Tuesday have surfaced.

In the photo, Prince William is seen driving to Buckingham Palace (while sporting a pair of dapper glasses) with Prince Harry in the passenger seat. Duchess Kate is in the back with the kiddies -- and it looks as though she's wearing a purple ensemble with her hair down.

It looks as though Princess Charlotte may be hiding -- but Prince George can be spotted, looking adorable as always.

Prince William, Duchess Kate and Prince Harry kicked off festivities Monday, attending a holiday charity party together -- where Middleton donned her most festive ensemble yet.

Tuesday's Christmas lunch may be the extent of William, Kate and the kids' celebration with the Queen, as it was reported last week that they are spending Christmas with the Middletons.
