Kate's private secretary even joined in.
Prince William and Kate Middleton had the an adorable moment today while leaving a Christmas party at Kensington Palace. The Duke and Duchess of Cambridge held a holiday celebration for the families and children of the Royal Air Force personnel serving in Cyprus.
After an afternoon of craft-making with guests, the Duke and Duchess were were caught in the middle of a sweet mini snowball fight while leaving the event, initiated by some of those gathered to send off the royal couple.
William and Kate, along with Kate's private secretary, Catherin Quinn, waved goodbye to the children and walked through a snow machine. A few bystanders on the sidelines threw (fake) snowballs at the couple, which the Duke and Duchess caught in their arms. They were good sports, and appeared to smile and laugh at the interaction. Quinn lingered behind the couple, and even playfully threw a snowball back at the kids, according to royal reporters.
It appears Kate tossed some snowballs around inside the party, too.
The couple also had plenty of sweet moments during the event. Prince William was seen making crafts with the children, and Kate was seen talking to some of the kids and moms.
Kate also gave a short but sweet speech to the families attending the festivities. "Not only are we grateful for you coming here to join our party, but also for the sacrifices you make on a daily basis on behalf of the nation," she said.
"As someone whose husband has served, I know how hard it feels when a loved one leaves home to the job they trained for," she added. The Duke of Cambridge was in the British military for more than seven years.
The Duchess of Cambridge also included holiday wishes for her guests. "And if it's not too early, Merry Christmas to you all," she said at the end of her speech.
