Hugh Richard Louis Grosvenor, known to friends as Hughie, became the Duke of Westminster after his 64-year-old dad Gerald died earlier this year.
The former Newcastle University student is a familiar face among the royals, having become the youngest godfather to Prince George in 2013.
As the seventh Duke Hugh was expected to inherit the family”s whopping £9billion wealth which includes the Grosvenor Estate property portfolio.
The impressive portfolio, which is jokingly referred to as “half of London”, includes 100 acres of real estate in Mayfair and 200 acres of Belgravia.
Despite his flash party Hugh has generally opted to stay away from the spotlight.
After studying land management at university, Hugh now works as an accounts manager for a bio-fuels company.
He was pictured out partying like any other student during his time at uni, and pals said he was down to Earth despite his family”s huge wealth.
One friend said: “You”d never have known that his dad was a billionaire.”
Dad Gerald, who was named the 68th richest billionaire in the world, suffered a fatal heart attack at the family”s Abbeystead Estate in August.
Family and friends, including royals Wills and Kate, attended his funeral in Chester yesterday.
More than 1,400 people turned out to pay tribute to the sixth Duke of Westminster.
During the service Hugh read his father”s favourite poem If by Rudyard Kipling before the congregation and the choir sang hymns.
