Tim Gragam/CorbisThere was truly nobody like Princess Diana, and there probably never will be.
The stunning royal, who tragically died in a car accident nearly 18 years ago, would have celebrated her 54th birthday today. While the beloved icon and "people's princess," as she was affectionately known, has since passed away, her legacy lives on through her sons Prince William, 33, and Prince Harry, 30, as well as her adorable grandchildren, Prince George and Princess Charlotte.
In addition, Diana would have most likely been delighted to know that Mario Testino, famous for taking the last official portraits of Diana, is slotted to document Charlotte's upcoming royal christening.
During her time in the spotlight, Lady Di redefined royalty with fearless fashion, poise and innate relatability. Celebrate her life with a look back at her most iconic moments.
