See Princess Charlotte's Beautiful Christening Photos Shot by Mario Testino

Princess Charlotte is adorable in her official christening photos.

Just four days after Princess Charlotte was christened at the Church of St. Mary Magdalene in Norfolk, England, the first official photos are being made public. Shot by famed photographer Mario Testino, the princess is seen in the arms of her glowing mother.

And even the famed photographer, who's pretty much photographed every A-list star in the world, can't help but be impressed by the Duke and Duchess of Cambridge and their adorable two-month-old daughter.

"Photographing Princess Charlotte's christening was an amazing experience," Testino tells ET. "What impressed me the most was the energy of the family, and of that between the Duke and Duchess. One sees how solid they are together and one gets a sense of their strong family values."

Testino also observes that the royal family -- particularly Queen Elizabeth II and her son Prince Charles, and grandson Prince William -- is close.

"It was incredible to be able to document four generations of the British Royal Family together -- the monarch and three heirs to the throne -- and very heartwarming to see the close relationship between them all," he says.

Princess Charlotte was baptized  at the same church that Charlotte's late grandmother, Princess Diana, was baptized in back in 1961. She also wore the same historic gown her big brother, Prince George, wore at his christening.

And it turns out even Prince George's look was a throwback -- his adorable outfit, consisting of a pair of short red trousers and a white top, was very similar to the one his father wore as a child on his first visit to meet newborn Harry at the hospital back in 1984.
