King Charles’ other alleged mistress — Lady Dale Tryon’s heartbreaking life

It sounds like King Charles III was quite the ladies’ man back in the day.

While the monarch, 74, was famously married to the late Princess Diana through the ’80s and early ’90s, he additionally had a longtime affair with Camilla Parker Bowles — now queen.

Despite those two very significant relationships, Charles also allegedly had another rendezvous: with Lady Dale “Kanga” Tryon.

While not much has been written about Lady Tryon, she made a name for herself in royal social circles through her work as a fashion designer.

Charles — who gave the socialite the nickname “Kanga” due to her Australian roots — once called her “the only woman who ever really understood me.”

She was thought to be one of the first gals to sleep with Charles — before his high-profile associations with Camilla, 75, and Diana.

He became pals with Dale when she married Anthony Tryon, 3rd Baron Tryon, in 1973.

The Baron had been a part of then-Prince Charles’ in-crowd, and Dale got to know the royal more intimately through her spouse.

However, she had actually crossed paths with Charles for the first time back in 1966 — when she met him at a school dance in Victoria, Melbourne, where she grew up.

But before dipping her toes into the world of tiaras and gold, Dale made the grand move to the United Kingdom from the land down under so she could work on her couture label in 1972 — just a year before her wedding.

Over the course of their marriage, the Tryons welcomed four children together and subsequently divorced in 1997.

Her life was even chronicled in a 2008 Channel 4 documentary, “Prince Charles’ Other Mistress,” detailing her purported love with Charles and the tragedies she faced.

The film alleged that Charles and Dale’s relationship arose while the former was still seeing Camilla — who had married military man Andrew Parker Bowles in 1973.

The heir apparent — at the time — was enjoying his singledom, having leaped from Dale to Camilla and back again.

The former Duchess of Cornwall and the businesswoman were reportedly “serious rivals” and hated each other’s guts.

When Dale gave birth to her second child — actually named Charles — in 1976, Queen Elizabeth’s oldest son became the boy’s godfather.

But when Charles tied the knot with Diana in July 1981, his alleged love triangle with the aforementioned two women came to a halt.

Dale apparently struck up a friendship with Lady Di — who died in 1997 — but reportedly remained at odds with Camilla.

“[Camilla] was the enemy, and on the basis that my enemy’s enemy is my friend, [Diana] could see that there was some purpose in having an alliance with Dale,” royal expert Christopher Wilson said in the Channel 4 special.

The Princess of Wales even sported one of Dale’s designs at the 1985 Live Aid concert.

The Tryon family denied any claims of an affair between Dale and Charles, the documentary noted.

It has been widely reported that when Charles was attending a polo match in the mid-1990s, Dale tried to pursue him while she was confined to a wheelchair.

She attempted to rekindle their friendship, but the royal wasn’t having it.

According to Tina Brown’s 2022 book “The Palace Papers,” Charles released a statement a short time later, attempting to distance himself and stating that he and his former lover were just acquaintances.

He even claimed that they only spoke “once or twice a year” and he wanted to push her away — though Brown wrote that Charles still “loved her breezy, colonial frankness.”

Because of her supposed “unhinged” mental state, Baron Tryon — who died in 2018 — had Dale sectioned under the Mental Health Act in June 1997 and started drawing up divorce papers.

There were also whispers that Dale used her relationship with Charles as publicity for her “Kanga” line in the 1970s and early 1980s.

Her lifespan was marred with various sicknesses, having suffered from illnesses such as Perthes disease and spina bifida throughout her childhood.

In 1993, she was diagnosed with uterine cancer and later battled alcohol and drug addiction.

Dale made the journey to a rehabilitation facility in Surrey, called Farm Place, in 1996, after abusing painkillers, large amounts of vodka and Champagne in order to deal with her cancer.

While at the treatment center, she fell from a window and severely injured herself; she fractured her skull, injured her spine and was left paralyzed.

She was forced to use a wheelchair for the last 18 months of her life.

Before her death in November 1997 from septicemia, or blood poisoning — two months after Diana’s tragic passing — Dale jetted off to Australia and India.

But when she returned to London, she was admitted to King Edward VII’s Hospital, where she passed soon after — less than two months shy of her 50th birthday.

She was buried in England and her $1.6 million estate was left for her children.
