Kate Middleton, along with the rest of the royal family, yesterday celebrated Queen Elizabeth II's 88th birthday in London. The family honored the Queen with a Trooping the Colour parade, and were then escorted to the balcony of the Buckingham Palace. She was joined by husband Prince Philip, Duke of Edinburgh, Duchess Kate, Prince William, Prince Harry, son Prince Charles and his wife Camila, the Duchess of Cornwall.
The Queen looked appropriately regal in a blue satin silk coat and a white hat with a navy trim. She smiled as she waved to the thousands of Brits standing below. Prince Harry, meanwhile, shared several laughs with sister-in-law Middleton, 32, and older brother William, 31. See more photos below
