Kate Middleton is keeping the memory of Princess Diana close to her heart during King Charles III’s Trooping the Colour. 

The Princess of Wales stunned in an elegant green coat dress with bejeweled embellishments.

While Kate made her first appearance at Trooping the Colour as the Princess of Wales, she came dressed to the occasion with her gold Cartier shamrock brooch and completed her look with diamond drop earrings that previously belonged to her late mother-in-law Princess Diana. 

TROOPING THE COLOUR KICKS OFF KING CHARLES’ OFFICIAL BIRTHDAY PARADE AS MONARCH

Princess Diana wore the diamond earrings during a royal event in 1995. She was photographed wearing a full-length sleeveless black evening dress while holding a bouquet of flowers.

During the Trooping of Colour, Princess Kate topped off her look with a matching green hat to go with her gorgeous ensemble. 

As the Princess of Wales honored Princess Diana, her remarkable green outfit choice and shamrock brooch was a nod to her new colonelcy of the Irish Guards.

Last December, King Charles appointed Princess Kate to colonel of the Irish Guards. The title previously belonged to Prince William.

The Trooping of Colour concluded with the royal family gathering out on the palace balcony. The Royal Air Force soared to the skies and performed a colorful flypast in a sweeping finale. There was also a 41-gun salute fired from nearby Green Park.

A Florida sheriff's deputy risked his life to rescue a man who was trapped in floodwaters, with both men sucked underwater into a drainage pipe, gripping video shows. 

Escambia County Deputy William Hollingsworth and the citizen in distress were carried nearly 100 feet underwater beneath a four-lane highway before resurfacing on the other side, the Escambia County Sheriff's Office said Friday.

For several days now, Escambia County has been hit with severe weather and torrential downpours, which peaked early Friday morning.

Hollingsworth was on patrol to assist stranded motorists who were caught in rapidly rising waters, the sheriff's office said. During his patrol, the deputy came across a man with a disabled vehicle. 

MAN FALLS MORE THAN 4,000 FEET FROM GRAND CANYON SKYWALK TO HIS DEATH

Body camera footage captured the terrifying moment Hollingsworth was caught by the floodwaters mid-rescue and dragged underwater through a drainage pipe by the side of the road.

For nearly 30 seconds, roaring water drowns out all other noise as Hollingsworth appears to tumble through darkness. By some miracle, he and the man in distress resurfaced on the other side of the highway, where the drainage pipe had an outlet.

Video shows Hollingsworth immediately rushed to the other man's aid once he was able. "You okay, buddy? Can you believe what just happened to us?" the amazed and terrified deputy exclaims. 

He tells the man to breathe and helps him to his feet. "I almost died," the shocked citizen says.

Hollingsworth was able to help the man to safety and called other police officers for assistance. The man who was in distress thanked the officers profusely.

"When I came out, you were right there," he tells Hollingsworth. 

The Escambia County Sheriff's Office said the footage is an example of the "exceptional courage displayed by the men and women of law enforcement every day." 

Many Facebook users commented on the sheriff's office statement, praising the valor of the deputy and thanking the police for risking their lives to keep citizens safe.
