With the U.K. in its third lockdown of the pandemic, birthdays can be a hard thing to celebrate. But Prince George, 7, and Prince Louis, 2, along with sister Princess Charlotte, 5, found a fun way to honor their mom Kate Middleton on her 39th birthday on Saturday. The kids and dad Prince William threw their mother a very British celebration by having a tea party at their country home Anmer Hall in Norfolk, Peoplereports, and party prep was strictly in the hands of William and the kids.
