In a recent interview with Access Hollywood, the former American Idol star divulged how the Duke of Sussex has bonded with the Canadian music producer.
"My husband has a really, really beautiful relationship with Harry," she revealed.
"They're like, they're so cute," Katharine continued. "They're like father and son."
The singer added after she reconnected with former schoolmate Duchess Meghan, the four of them have been keeping in touch.
"We just stay in touch with them," Katharine elaborated. "But mostly, Meghan and I knew each other from childhood, but really Harry and my husband are friends, so it's really nice."
Katharine's comments come after David reportedly helped the Duke and Duchess of Sussex find the estate in North Saanich, B.C. where they spent their six-week extended break from royal duties and enjoyed "private family time" with Archie earlier this year as they transitioned out of their senior royal royals.
"I felt honoured that I was able to help Meghan there, because I’m a Canadian and we’re a Commonwealth country, we’re the Crown's," David told the Daily Mail in January. "It’s important to us, so I grew up with that kind of sentiment."
The young family has mostly kept out of the spotlight, but have helped in the battle with COVID-19 by delivering food to people with life-threatening illnesses in the Los Angeles area. On May 6, the duke and duchess celebrated Archie's milestone first birthday by sharing a sweet video via the Save the Children UK Instagram of Meghan reading with her infant son.

In the interview, Katharine also revealed the hopes and wishes from herself and on behalf of her husband for Harry and Meghan.
"We just want them to end up wherever they feel safest and happiest," she said.
