The 36-year-old actress joined her fiance, Prince Harry, and his brother and sister-in-law, Prince William and Kate Middleton, for the inaugural Royal Foundation Forum on Wednesday in London, England, and opened up about the bond she already shares with the royal family.
After talking about their philanthropic efforts and what they hope to achieve with their new organization, the couples were asked if they have disagreements when working with one another.
"Oh yes," William, 35, quipped. "Healthy disagreements," Harry chimed in.
"I think it's really good we've got four different personalities," he noted. "We've all got that same passion to want to make a difference, but different opinions. I think those opinions work really, really well. Working as family does have its challenges, of course. The fact that everyone's laughing shows that everyone knows exactly what it's like."
Harry, 33, jokingly added, "We're stuck together for the rest of our lives."
