Prince William and Kate Middleton joined the royal family at church services in Windsor earlier today to celebrate Prince Philip's 90th birthday. It's the second day in a row of celebrations for the newlyweds after yesterday's Trooping the Colour parade for the Queen's 85th birthday. Kate joined Harry and Camilla Parker Bowles in a carriage during Saturday's event while William and his father, Prince Charles, rode horseback. It's been a big week of fashion moments for Kate, who arrived in a stunning floor-length Jenny Packham gown for the ARK dinner on Thursday and dressed up to join her sister Pippa Middleton for a friend's wedding as well.
