Prince William, Kate Middleton, and Prince Harry looked especially cheery when they attended a Christmas party for volunteers at The Mix youth service, a charity that is part of their Heads Together initiative, in London on Monday. While the princes looked dapper in blue suits, Kate was completely festive in a green and red dress. As the trio prepares for their Christmas break later this week, William told a DJ at the party that Prince George and Princess Charlotte are really looking forward to the holidays. "He said the kids are really looking forward to Christmas and George is already ripping open his presents," A. J. King told People. "They're looking forward to downtime and a chill with the family." The royal couple are set to take their children for their first Christmas at the Middletons' home in Bucklebury, in rural Berkshire. Hopefully the little ones will like the teddy bears Kate was gifted with earlier this month!
