Princess Charlotte's Christening: Mario Testino Picked as Photographer

Princess Charlotte will be christened July 5.

— -- The Duchess of Cambridge famously snapped the first photos released of her son and newborn daughter together, but the royal family has tapped a world-renowned photographer to record their next milestone.

The nearly 2-month-old Princess Charlotte Elizabeth Diana will be christened July 5 at St. Mary Magdalene Church on the Sandringham Estate of her great-grandmother, Queen Elizabeth II.

The church is the same spot where her grandmother, Princess Diana of Wales, was baptized in 1961, and is near the family's country estate, Anmer Hall, that has been their home much of the time since Princess Charlotte's May 2 birth.

Kensington Palace announced Monday that the paddock outside the church will be open to the public, meaning well-wishers may have a chance to see Kate, William, Charlotte and her big brother, nearly 2-year-old Prince George, as they walk inside.

Prince George’s baptism took place in 2013 in an intimate service at St. James’s Palace in London, with only immediate family, godparents and their spouses in attendance.

Princess Charlotte will wear the same christening gown worn by Prince George. The gown, remade by the queen's dresser, Angela Kelly, in 2004, is an exact replica of the gown first commissioned by Queen Victoria 174 years ago and has been used for every generation of royal infants, totaling 62 royal babies in all.

Since her birth last month at St. Mary’s Hospital in London, Princess Charlotte has only been seen by the public twice: once when she left the hospital with her parents, and the second time in official photos of her and Prince George together, taken by their mother, Duchess Kate.
