Prince William had a notably strong reaction when his relationship with Kate Middleton was unexpectedly exposed during a university dinner party. The couple, who met while studying at St Andrews, initially started as friends before their relationship turned romantic. Reports suggest that Kate caught William’s attention when she wore a semi-sheer dress at a charity fashion show in 2002. By the end of that year, they were living together with two other students. According to royal biographer Robert Jobson’s book *Catherine, the Princess of Wales*, their relationship was well-known among their peers, though not publicly acknowledged.
The disclosure came from one of William’s former girlfriends, Carly Massy-Birch. During a lively game of ‘Never Have I Ever’ at a dinner party with mutual friends, including Carly, she reportedly made an inadvertent revelation about the couple. Carly’s comment that she had never dated two people present at the party was understood to refer to William, as Kate was seated beside him.
This moment, described as revealing by Jobson, led to a visible reaction from William, who was clearly displeased. According to Katie Nicholl, another royal author who covered the event in her 2013 book *Kate: The Future Queen*, a guest recounted William’s angry reaction as he shot a stern look at Carly and muttered his disbelief about the comment.
Despite the initial embarrassment, the incident confirmed the couple’s relationship publicly for the first time. William managed to move past the awkward situation, and he and Kate maintained their friendship with Carly, who was even invited to their wedding at Westminster Abbey in 2011.
Carly and William’s brief romance occurred during his first semester at university, lasting less than two months, with their social interactions including dinner parties. Carly later described their relationship as typical of university life, noting that their connection was more about companionship than deep romance.
