Prince William, Kate Middleton and Prince Harry Among Royals Attending Pre-Christmas Lunch at Buckingham Palace

Prince William, Kate Middleton and Prince Harry Among Royals Attending Pre-Christmas Lunch at Buckingham Palace, The royals have officially kicked off the holiday season!

Prince William, Kate Middleton and Prince Harry were among the royally famous faces arriving at Buckingham Palace today for the annual pre-Christmas lunch. The Duke and Duchess of Cambridge appeared in good spirits as they arrived together in a car driven by William, attending the celebration sans their one-year-old son Prince George.

Both Will and Kate looked lovely for the occasion with the 32-year-old father rocking a pair of black glasses teamed with a sharp suit while his expectant wife stunned in a festive red dress, complete with sparkly chandelier earrings. And of course, Kate's enviable locks were styled to perfection, despite her hubby—who has previously been dubbed the "hairless heir"—recently joking that Kate's tresses are a "nightmare."

No surprise, Prince Harry also looked dapper as ever as he rolled up to Buckingham Palace, sporting a navy blue suit and matching tie, while seated beside a member of his security team.

And Will, Kate and Harry certainly weren't the only notable names in attendance—in fact, the guest list reads like a who's who of the English monarchy.

Prince Charles, Princess Beatrice, Prince Edward, Prince and Princess Michael of Kent, their daughter Lady Gabriella Windsor, and Prince Richard, Duke of Gloucester were all present at the holiday lunch in addition to Lady Sarah Chatto and her husband Daniel, Princess Anne and the Earl of Wessex, as well as Anne's son Peter Phillips, whose wife, Autumn Kelly, happily waved to onlookers as they drove on to the property.

Buckingham Palace's annual pre-Christmas lunch is a royal tradition upheld by the Queen, which allows members of the royal extended family to connect ahead of the holidays.

And while Queen Elizabeth II is certainly a top notch host, it is being reported that Will and Kate will host the annual Christmas dinner at their recently remodeled estate in Norfolk. The event is expected to be held in tandem with a housewarming party at Amner Hall, which recently was renovated under Kate's direction.
