Who is Olivia Henson? The woman marrying Britain's 'most eligible bachelor' today.

On June 7 UK time, Britain’s most eligible — and richest — bachelor will be officially off the market, marrying a woman you've probably never heard of, until now. 

With strong ties to the royal family, Hugh Grosvenor, the Duke of Westminster, is far richer, worth almost $20 billion.  

King Charles is Grosvenor’s godfather, while William and Harry are lifelong friends, and yet he remains, for the most part, under the radar. 

So does his future wife, Olivia Henson, who was introduced to the Duke two years ago through friends. 

Watch: royal wedding dos and don'ts. Post continues below. 

The 30-year-old seems to share the same down-to-earth personality as her husband-to-be, with the pair sharing a fittingly casual photo to announce their recent engagement. 

Here's everything we know about the woman becoming the Duchess of Westminster.

Who is Olivia Henson?

Not much is known about the woman whose wedding will no doubt stop the world in its tracks, as she becomes the Duchess of Westminster.

We do know she’s a senior account manager at Belazu, an environmentally friendly London-based B-corp, that imports high-quality ingredients from across Europe.

Henson's education began at the private Dragon School in Oxford before she was off to Marlborough College, where alumni include Kate and Pippa Middleton. 

She reportedly also studied Hispanic and Italian at Trinity College.

Who is Hugh Grosvenor?

Hugh Grosvenor earned his title and riches at just 25 years old following the death of his father, the sixth Duke. 

Despite having older sisters, Grosvenor inherited the entire fortune due to an old custom called primogeniture, which favours the male heir. 

He went to school at a local state primary, before studying at the small private school, Mostyn House and then Ellesmere College. 

He then went on to study countryside management at Newcastle University, before joining the family business.

He is now chair of the Grosvenor Group and the Westminster Foundation, which the family use to disburse their charitable donations.

Both Henson and Grosvenor have minimal online histories, aside from the extravagant affair that was the Duke’s 21st birthday, attended by Prince Harry and reportedly costing more than $9.5 million.

The wedding will take place on Friday, June 7, at Chester Cathedral followed by a reception at Grosvenor's 11,000-acre estate, Eaton Hall. 

The venues are expected to be decorated with 100,000 flowers and there will be 400 people in attendance, including Prince William who will serve as an usher.

Originally, Prince Harry was invited to attend the wedding. But apparently, an agreement has been reached, with both parties acknowledging it would be better if he didn't.

According to The Times UK, Hughie is "one of only a few friends who has remained close to both the Prince of Wales and the Duke of Sussex despite the brothers' increasingly bitter public feud".

"Harry was invited but then agreed to stay away," the publication reported. 

"The Duke's diplomacy then cleared the way for William to perform the role of usher during Friday's ceremony — a job that would have been beyond awkward if he was obliged to show Harry to his pew."

Princess Catherine will not be attending, while she continues to undergo cancer treatment, and the King is not expected to attend either.
