Prince Harry’s relationship with Prince William isn’t the only dynamic that has changed over the years. The Duke of Sussex’s bond with his sister-in-law, Princess Kate, has gone through its own changes following his and Meghan Markle’s royal exit.
While Harry always had kind words for his sister-in-law — “I’ve known Kate for years, and it’s fantastic that she is becoming part of the family,” he gushed after William and Kate’s engagement in 2010 — their relationship grew rockier as he publicly spoke out about their estrangement.
As Harry and Meghan began to discuss their ups and downs with The Firm — first via a tell-all interview on CBS in March 2021 and again in their six-episode Netflix show — sources told Us that both William and Kate weren’t thrilled with the airing of dirty laundry.
“I think that the idea that Kate’s being dragged into this will be upsetting for Kate who behind the scenes has tried really hard to be a peacemaker between William and Harry,” royal expert Kate Nicholl added during an interview with Entertainment Tonight in 2021. “She has been deeply saddened by the brothers’ falling out. Don’t forget she was incredibly close to Harry herself.”

She was a good match for my older brother. »
