Zara Phillips wins silver Olympics medal; Prince William, Kate Middleton and Prince Harry there to cheer her on

zara-phillips-summer-olympics-2012.jpg Zara Phillips is not only Queen Elizabeth's granddaughter and cousin to heir to the throne Prince William, but now she's an Olympic medal winner. The 31-year-old competes in the equestrian events at the Summer Olympics and Tuesday (July 31), she won a silver medal in the Team Eventing Jumping, as one of five riders for Great Britain.

Unfortunately, when it came time for the Individual Eventing Jumping, Phillips and her horse, High Kingdom, finished in 8th, so no individual medal just yet. But Phillips still has several more equestrian events to compete in.

Phillips has quite the Olympic pedigree. Her mother, Princess Anne, Queen Elizabeth's second child and only daughter, competed on the Great Britain equestrian team in the 1976 Montreal Games, and her father, Captain Mark Phillips, competed for the Great Britain equestrian team in the 1972 and 1988 Olympics, earning a gold and a silver, respectively.

Prince William and Prince Harry were on hand to root for her Tuesday morning, along with Catherine, Duchess of Cambridge (pictured below). The Princes were also at the men's gymnastics finals Monday night, cheering their countrymen on to a bronze medal.
