"We're stuck together for the rest of our lives," Prince Harry jokingly said in an event he attended together with fiancée Meghan Markle, Prince William, and Kate Middleton.

The younger members of the British Royal Family attended the first annual Royal Foundation Forum just 80 days before Prince Harry wed Hollywood actress Meghan Markle.

In an interview, the spare to the throne said that while he expects to do royal work alongside his family, he is excited to share similar philanthropic missions. Prince Harry was also casual as he shared some disagreements he had with the family.

Prince Harry described their opposing views "thick and fast" that he could not even remember what it was all about.

"We've got four different personalities and we've all got that same basic passion to want to make a difference," Prince Harry said.

Shining Light On Women Empowerment

As she sat on stage together with her future in-laws, Markle hinted on her intended role once she becomes an official member of the Windsor Family.

Markle said that her primary focus would be "shining light" on women rights, consequently empowering female adults and young girls. She explained that women have evolved to have their own voice, but that voice is yet to be listened to.

"I think right now in the climate we are seeing so many campaigns, I mean #MeToo and Time's Up, and there is no better time to really continue to shine a light on women feeling empowered, and people really helping to support them — men included," Markle said.

"I mean, it makes such a tremendous difference. So ... I guess we wait a couple of months and we can hit the ground running," she continued.

Destined To Multitask

Despite the Royal Family's busy schedule, Markle said she remains dedicated to campaigns supporting women empowerment. Prince Harry quipped that they are tied up with the preparations for the wedding on May 19, to which Markle said they can multitask.

Markle made rounds on social media as she shared an instance when her 11-year-old-self wrote Procter and Gamble citing an anti-feminist message on one of their commercials.

The 36-year-old Suits star highlighted her passion for humanitarian work, adding that Prince Harry also shares the same social perspective.

This is the second time Markle joined the members of the Royal Family in official gatherings. Previous practices caution on bringing a fiancé to family events until after the wedding.

The Royal Foundation Forum supports the Heads Together mental health program and the Invictus Games for the injured soldiers.
