Princess Charlotte - Growing Up ROYAL

Inside the life of a modern princess who's mature beyond her years and just like her mother, Princess Kate!

Princess Charlotte's big smile said it all. As Princess Kate descended the stairs inside London's All England Lawn Tennis and Croquet Club to watch the Wimbledon men's final on July 14 marking her second public appearance since revealing in March that she's being treated spectators, for cancer including Tom Cruise and Julia Roberts, erupted in cheers and applause and leapt to their feet. Charlotte took in the standing ovation from her seat in the royal box at Centre Court, gazing up at her mother adoringly.

"It's clear Charlotte feels so proud to be Kate's daughter," says a royals source. "And she loves doing special things with her mom, like attending Wimbledon. She really seems to understand how lucky she is to get to have these incredible experiences." That's all thanks to her parents. While the Prince and Princess of Wales, both 42, are raising Charlotte, 9, and brothers Prince George, 11, and Prince Louis, 6, as heirs to Britain's throne, they're also trying to ensure that the kids' childhoods are as grounded as they are magical. "Charlotte, in particular, has grown up so much over the past year," says the source. From her interactions with family members and the public to how she carries herself, "you can really see just how poised she is," adds the source. "She shows a maturity beyond her years. It's become more obvious that she understands her role and what it means to be in this family, but she's also still able to be a kid."
