The world of royalty, celebrity, and high-security protection is mourning a sudden loss that has left many in shock.

A figure known for his quiet strength and steadfast loyalty, he was often seen but rarely heard — a man who stood in the shadows of history while protecting some of the most famous names in the world.

Over the years, he worked with global icons in sport, film, and politics — and was especially close to a woman beloved by millions. Just recently, his passing was confirmed in a deeply emotional post from someone very close to him.

Only now is it being revealed that the man who passed away at the age of 63 is Lee Sansum, the former bodyguard of Princess Diana and her sons, Prince William and Prince Harry.

His wife Kate shared the heartbreaking news online, revealing that he died from a sudden heart attack at their home on Saturday morning. She described him as her “soul mate, hero, and the most amazing man” — a sentiment echoed by many who had the honor of knowing him.

Lee was more than a protector — he was a presence. Nicknamed “Rambo” by Diana herself, he held black belts in karate, jujitsu, and kickboxing, and also worked with celebrities like Stallone, Kidman, and Cruise.

He played a key role in Diana’s final summer, escorting her and her sons in St. Tropez just weeks before her tragic death in 1997. In his memoir, he recounted their bond, revealing touching memories — including teaching Prince Harry to drench paparazzi with a jet ski.
