Did Princess Diana’s sister Sarah Spencer date King Charles first?

We're all well acquainted with King Charles and Princess Diana's former relationship but did Diana's sister Sarah Spencer actually date Charles first?

• Princess Diana wasn't the only member of her family to date the Prince of Wales.
• Sarah Spencer and Prince Charles had a brief relationship back in 1977.
• In other royal news, Prince Charles reveals how baby Lilibet has reminded him of one of his lifelong passions.

Lovers of the hit Netflix show, The Crown, may wonder how much of The Crown is true - especially as some storylines are far too jaw-dropping to believe. One question on everyone's lips was did Princess Diana's sister Sarah Spencer, now known as Lady Sarah McCorquodale, have a relationship with King Charles first?

Incredibly, Diana's eldest sister lady Sarah, born Elizabeth Sarah Lavinia Spencer in 1955, did in fact date Charles before Diana. Princess Diana's sister Sarah and King Charles, who was then the Prince of Wales, had a brief relationship back in 1977 when the pair were in their twenties.

How did Sarah Spencer and Prince Charles' relationship end?

Per Tatler, their brief fling is believed to have ended after Sarah allegedly shared her royal romance with two reporters. During the conversation, she admitted to having an eating disorder, "thousands of boyfriends," and said that she wouldn't marry the Prince of Wales, "if he were the dustman or the King of England."

And that was that. So how did Charles and Diana end up meeting?

Well, it was Lady Sarah that introduced Charles to her younger sister at Althorp House, which was the Spencers’ ancestral home - and the grounds of which the late Princess Diana is now buried.

At the time of the initial meeting, Charles was there for a pheasant hunt and Sarah admitted afterward in an interview with the Guardian, “I introduced them; I’m Cupid.”

Aside from brother Charles, the Spencer sisters have another sister Cynthia Jane. They all grew up in close proximity to the royal family, with their home situated on the Sandringham Estate.

Their infant brother, John, died shortly after his birth one year before Diana was born.

Who is Princess Diana's sister Sarah Spencer now married to?

Sarah married Neil Edmund McCorquodale in 1980 and became Lady Sarah McCorquodale and they have three children George, Celia and Emily.

After her Diana's death, Sarah became the president of Diana, Princess of Wales Memorial Fund before it closed in 2012.

She has remained close to the royal family and often spends time with nephews, Diana's sons, Prince Harry and William, Prince of Wales.
