Not only can Prince William and Prince Harry count fellow royals among their high-flying family members.
They also have a host of glamorous jet-setting relatives that include a Dolce & Gabbana muse who married in a lavish Italian wedding, a model newlywed who recently tied the knot in South Africa and a cousin once dubbed "Prince Harry-lite".
They are all on their often forgotten Spencer side of their family, meaning they are all related to their late much-missed mother Princess Diana.
And with several of them leading very different lives to their royal relatives, here we take a look at exactly who they are...
Fashion muse
Among the most well-known of the current crop of Spencers is Diana's niece and William and Harry's younger cousin, Lady Kitty Spencer.
The 32-year-old hit the headlines in July 2021 when she married wealthy businessman Michael Lewis, 64, in a stunning three-day wedding in Italy.
She wore a series of gowns by Dolce & Gabbana with her main dress, which had an intricate floral lace design, a high neck, long sleeves and puffed shoulders, reportedly taking six months to create.
The couple exchanged their vows in front of celebrity guests that included singer Pixie Lott, and Idris Elba's wife Sabrina at the Villa Aldobrandini in Rome.
Kitty is Earl Spencer's oldest child and grew up in South Africa with her mother Victoria, her dad's former wife.
She read psychology at the University of Cape Town and has modelled for brands including Dolce & Gabbana, of which she has been a muse, and Bvlgari.
She also scored invites to the wedding of her cousins William and Harry and her Instagram account shows her at fashion shows in cities such as London and Milan.
Although the monarchy has now changed to put sons and daughters on an equal footing in terms of ascending to the throne, British primogeniture law has not been changed to peers such as dukes and earls.
So her father Earl Spencer's title will go to his eldest son Louis rather than Lady Kitty.
Glamorous twins
Sometimes joining their sister Kitty at events and parties are twins Lady Eliza and Lady Amelia Spencer.
They were born in 1992 and grew up in South Africa and were just five when their late aunt Diana died.
In 2021, they gave a rare joint interview in Tatler where they shared fond memories of their "incredibly warm, maternal and loving" aunt.
Speaking about Diana's death in 1997, Eliza said: "As a child, I realised the enormity of the loss for my father and family.
"It was only later that I came to understand the significance of the loss of her as a figure in the world."
"We always just knew her as our aunt. Growing up in South Africa, I really had very little idea of how significant she was in the world until I was much older."
Curiously, Amelia didn't attend cousin Harry wedding to Meghan in 2018, but Eliza was there. Both twins are models and are represented by Storm Management.
Earlier this week Amelia married her long-term boyfriend Greg Mallett in a mountain-top ceremony in Cape Town surrounded by her siblings.
Prince Harry-lite
Another member of the Spencer family is Kitty, Amelia and Eliza's younger brother Louis, who was once dubbed 'the world's most eligible bachelor' as well as ' Prince Harry lite'.
He is a fair few years younger than his royal cousins William and Harry but in the past, it has been reported that he is close to them.
Louis, 29, is said to be 'super private' but he played a starring role in sister Kitty's wedding, as he walked her down the aisle.
Last year, he graduated with a First from ArtsEd, an independent performing arts school based in Chiswick, and signed to talent agency Tavistock Wood.
He is listed on their client list as Louis John Lyons and joins other famous faces on the agency represents, which include Lily James, Rebel Wilson and Dustin Hoffman.
One day he will inherit the family's 13,500-acre Althorp estate in Northamptonshire as his father, Earl Spencer's heir apparent - despite having three older sisters.
Kitty previously said: "We've grown up understanding that it's Louis to inherit, and Louis will do an incredible job."
Head of the family
The current head of the Spencer family and holding the title of Earl Spencer is Diana's younger brother Charles.
He is the custodian of the family's Althorp estate in Northamptonshire and has been married three times.
As well as having children Kitty, Eliza, Amelia and Louis, he also has younger children Edmund, Lara and Charlotte.
Charles counts the late Queen as one of his godparents and was extremely close to Diana - delivering a moving eulogy at her funeral in Westminster Abbey in 1997.
However, when his eldest daughter Kitty wed this summer, there was reportedly no sign of her father at the nuptials.
An insider claimed the Earl may have skipped his daughter's big day due to a shoulder-related injury.
A source told MailOnline at the time: "Charles recently suffered an injury and perhaps that will be the reason for him not travelling, but it is just easier for everyone that he is not there."
It is believed he did not attend the wedding of Amelia either.
King Charles's ex
Lady Sarah McCorquodale is Diana's eldest sister and even briefly dated King Charles as a teenager.
She married Neil McCorquodale in 1980 and they have three children - Emily, George and Celia.
Diana was said to be close to Sarah and she sometimes accompanied her on engagements as a lady-in-waiting.
After Diana's death, she accompanied the then Prince of Wales alongside her other sister Jane to bring the princess back to the UK.
In 2019, she attended the christening of Harry's son Archie's christening and was at the unveiling of a statue of Diana in July 2021. It was reported she also attended Lilibet's christening in Montecito earlier this month.
Royal wedding star
Lady Jane Fellowes is another of Diana's older sisters and is married to Robert Fellowes - a former private secretary to the Queen.
She has three children - Laura, Alexander and Eleanor - and gave readings at the funeral of her sister as well as at nephew Prince Harry's wedding in 2018.
She too was at Archie and reportedly Lilibet's christenings and the unveiling of the Diana statue.
