Its not just Kate Middleton who has earned herself a title in the Middleton clan – sister Pippa has too.
Pippa Middleton married commoner James Matthews in May 2017 and, given he was not a Prince nor a member of the Royal Family, she remained simply as Pippa.
Her big sister Kate, however, married Prince William in April 2011 and instantly became Her Royal Highness AND Duchess Of Cambridge.
But it seems many fans of the Middleton sisters hadnt realised that Pippa is also due to bag herself a title in the distant future.
Pippa married into the supremely wealthy Matthews family.
James father, David Matthews is a hedge fund manager and businessman and he is where the secret lies.
As well as owning the luxurious A-list favourite Caribbean retreat Eden Rock, he owns the 10,000 acre estate Glen Affric in the Scottish Highlands, which includes as castle.
And its understood when David passes away, the estate gets given to James, being the eldest son at 42 compared to younger brother and Made In Chelsea star Spencer Matthews, 28.
This means Pippa, 34, will become Lady Glen Affric.
David currently holds the title of Laird of Glen Affric as he owns the estate in the Scottish highlands.
His son and Pippa will become the Laird and Lady on his death – and until then Pippa, as the heirs wife, will hold the courtesy title of Glen Affric the younger, The Express reported.
It is thought that David Matthews acquired the title, which is largely ceremonial, when he bought the Glen Affric estate in 2008.
The title even comes with its own red and green tartan.
Pippa and James, who is chief executive of Eden Rock Capital Management Group, got engaged in 2016 and married in 2017. They are now expecting their first child together.
Inside Eden Rock – the A-list Caribbean hotel owned by Spencer Matthews' parents Jane and David
Spencer Matthews' can't ever have found it hard impressing girlfriends when he was growing up – not with a luxurious family-owned Caribbean retreat at his fingertips.
Eden Rock Caribbean – the five-star resort and a favourite among the rich and famous – is owned by David and Jane Matthews, the reality TV star's mum and dad.
Spencer's parents – who are also the parents of James Matthews, the husband of Pippa Middleton – bought the resort back in 1995 after visiting St Barts for a family holiday.
The resort is situated on Saint Barthelemy island – aka, St Barts – and sits upon a quartzite bluff overlooking the Baie de Saint Jean.
In fact, it's ranked as the best hotel on the entire island of St Barts, so it's no surprise those flash with their cash love it.
We are, of course, talking about the rich, famous and glamorous celebrities who flock to the resort year after year – and not the reality TV kind that Spencer is well-versed with; the A-list kind who come from a sunny place called Hollywood.
Those that have holidayed in the 32-bedrooms and suite resort include the likes of Beyonce, Brad Pitt, Leonardo DiCaprio and Elton John, to name a few.
In its early days, when it was owned by St Barts politician Remy de Haenen, who died in 2008, it was regularly visited by the likes of Greta Garbo and Howard Hughes. Legend has it that Greta once checked into Eden Rock and ended up staying for three weeks she loved it so much.
Eden Rock even has its own artist-in-residence: Spencer's mum.
Zimbabwe-born Jane is an artist and a graduate of London University's Slade School of Art.
She opened The Eden Rock Gallery in the 1990s and it is a firm favourite among its clientele.
Eden Rock was badly damaged by Hurricane Irma in 2017 and, currently closed for repair work, it is due to reopen at the end of this year.
He and Jane bought the resort after he sold a car dealership business he bought in 1973 in a multi-million pound deal.
The pair had three children together – Spencer, James and Michael. However, tragically, Michael died in 1999 in a mountaineering accident at the top of Mount Everest
If Eden Rock wasn't enough, the Matthews also bought a Victorian Lodge in Glen Affric in Scotland in 2008.
David currently has the title Laird of Glen Affric and when James inherits it, Pippa will be able to match her sister, the Duchess Of Cambridge, in the title stakes as she'll be able to call herself Lady Glen Affric.
