Queen's Ceremonial Birthday: Kate Joins the Parade

Queen Elizabeth II has marked her ceremonial birthday with the traditional "Trooping the Color" parade in the heart of London. The queen turned 89 on April 21, her actual birth date, which is traditionally marked in private, with a public celebration held in June, when London's fickle weather is more likely to be favorable. She was joined by senior royals including the Duchess of Cambridge, who made her first appearance in public since leaving the hospital with newborn, Princess Charlotte six weeks ago. Prince Charles, Prince William and Princess Anne were on horseback for the annual ceremony. Throngs gathered outside Buckingham Palace to view the festivities and to see the royals gathered on the palace balcony.
