Prince William and Kate Middleton's college classmate dead after 100-foot rooftop fall

Ben Duncan, who appeared on Britain's "Big Brother" and knew Prince William and Kate Middleton in college, has died after falling from a London rooftop building.

A British reality star and socialite who was also a classmate of Prince William and Kate Middleton during their college days, died Thursday after a fall from a rooftop, London police confirmed to Fox News Digital Tuesday.

"Officers responded to concerns for a man on the roof of a building in Cockspur Street, Westminster at 23:02hrs on Thursday, 30 October," a spokesperson for the Metropolitan Police told Fox News Digital.

"The man sadly fell from height. Despite the best efforts from the London Ambulance Service, he was sadly pronounced dead at the scene. His death is being as unexpected but non-suspicious."

He reportedly fell from the posh Trafalgar St. James Hotel. The fall was about 100 feet, according to People magazine.

Duncan, 45, who appeared on reality shows like Britain’s "Big Brother," attended University of St. Andrews in Scotland at the same time William and Middleton were there and began dating.

He was an acquaintance of the couple while they were at St. Andrews and was one of the first people to know they were an item, according to the Daily Mail, which was first to report the story.

He was also at the school’s infamous student fashion show during which Middleton reportedly caught William’s eye when she walked the runway in a sheer dress.

"It was the end of their first year," Duncan previously told the Daily Mail of the fashion show. "I was there, and in person there were a lot of attractive girls. She was in a very daring dress, in a sheer stocking-like dress. He was sitting front row, and his eyes were like stalks.

"She brushed by him on the way to the catwalk, and things were never the same again — the whole history of the monarchy had been altered."
