The night Prince William’s relationship with Kate Middleton was outed during a game of ‘never have I ever’

It was the royal romance that remained out of the public eye for more than two years.

Prince William’s relationship with Kate Middleton at the University of St Andrews began as a friendship and then grew into something more in 2002.

Though not announced officially to the world until 2005, ‘it was an open secret’ among the student community, Robert Jobson writes in his new biography of the Princess of Wales.

But it was not until the they played a drinking game at a dinner party that the pair acknowledged it to others.

Carly Massy-Birch, who William briefly dated during his first term, asked a question during a round of ‘Never Have I Ever’ that would uncover his relationship with Kate.
