According to The Sun, the Sussex's and the Cambridge's will come face-to-face for the first time since Meghan and Harry's explosive ITV documentary, with sources saying the Palace is desperate to make sure everything runs smoothly for Remembrance Sunday.
Sources also told The Sun that Palace aides are hoping the event will pave the way for both couples to "reflect".
Remembrance Sunday, on November 10, will be the first event that all senior members of the Royal family will attend since Meghan and Harry revealed their wish to move away from England, and that family relations were currently tense.
A source told The Sun: "Palace staff are keen to ensure that the family come together to pay their respects and that the focus is on the brave souls who lost their lives for their country.
"Remembrance Day is an especially poignant event for all of the members of the royal family, but especially for Prince Harry who served in Afghanistan.
"There is a general sense of hope that this day will put things in perspective and allow senior family members time to reflect on what the important things in life really are."
On their now infamous documentary, Harry spoke candidly about his waning relationship with his brother.
"Part of this role, part of this job and this family being under the pressure it is under, inevitably stuff happens," Harry began.
"But look, we are brothers, we will always be brothers. We are certainly on different paths at the moment but I will always be there for him and, as I know, he will always be there for me."
Harry continued: "We don’t see as much as we used to because we are so busy but I love him dearly and the majority of stuff is created out of nothing.
"As brothers, you have good days, you have bad days."
