Before Prince William married Kate Middleton and Prince Harry married Meghan Markle, they were just a pair of rambunctious teenage boys, who Queen Elizabeth struggled to understand.

During their younger days, William and Harry exhibited reckless behavior and partied hard with their girlfriends at UK hotspots like Boujis, where they were often photographed by the paparazzi.

In Katie Nicholl’s book “William and Harry,” a source told the author the Queen wasn’t happy about her grandsons’ wild behavior. “The Queen cannot understand why her grandchildren go to places where they will be photographed and attract attention,” the insider revealed.

At one point, the Princes’ grandfather stepped in and told the boys to take a break from their wild nights. “Philip has told William and Harry to stay away from Boujis for a bit,” Nicholl wrote.

Despite the advice, Harry still managed to get into trouble in 2001, when he was caught smoking marijuana and underage drinking. Although the teen wasn’t arrested, the incident left his grandparents in “despair.”

Meanwhile, Prince William considered dropping out of the University of St Andrews but after receiving a stern scolding from Prince Philip, he continued his education.

Although William and Harry were all about having a good time during their youth, it appears the men have settled into their roles as Princes and now, husbands.
