"Mrs. Michael Tindall today safely delivered a baby girl at Gloucestershire Royal Hospital," Buckingham Palace announced in a statement. "Mr. Tindall was present at the birth. The weight of the baby was 7lbs 12oz (3.5 kg.)

"The Queen, The Duke of Edinburgh, The Princess Royal, Captain Mark Phillips and Mike's parents, Mr Phillip and Mrs Linda Tindall, have been informed and are delighted with the news. The baby's name will be confirmed in due course."

The baby is Queen Elizabeth II's fourth great grandchild — which makes her 16th in line to the throne.

This is an exciting time for the royal family. Zara is the cousin of Princes William and Harry, the daughter of Princess Royal Anne. She's also a medal-winning Olympic equestrian. In fact, days before she announced her pregnancy, she fell off her horse at the Barbury International Eventing and Show.
