The event will celebrate the life of the late Princess, who would have turned 60 this year.
The 100 strong guest list will feature some big names.
Friends and family close to Princess Diana such as Sir Elton John will all be in attendance.
No doubt Harry will be keen to join his brother, Prince William, to celebrate the life of his mother.
The event was supposed to take place after the unveiling of the Diana statue on the late princess’s birthday on July 1.
It will now happen on October 19 at Kensington Palace.
The event is scheduled to last an hour and it has been designed to honour Lady Di’s legacy.
Can the Sussexes travel to the UK?
Covid restrictions allowed Harry to travel from his home in California to the UK, for the scaled-down unveiling of his mother’s statue in July.
Harry joined his brother William along with close friends and family for the poignant unveiling of the statue in the sunken gardens at Kensington, said to be a favourite spot of Lady Di’s.
Meghan did not accompany him as she had just given birth to their daughter.
The Sussexes could attend the postponed reception under the current Covid restrictions.
Travel restrictions between the US and UK have been relaxed so the pair would not have to quarantine.
Will Harry and Meghan bring their children to the UK?
So far the Sussexes have been keen to shield their children from the public eye.
But the couple could use this opportunity to allow the Queen to meet her new granddaughter.
A royal insider told The Sun: “No one knows what Harry’s decision is but there are rumblings that he may come with Meghan and their two children.”
But it is understood the Sussexes have yet to inform palace officials or event organisers of any plans to attend the event.
