Prince Harry spent no time with his brother the Duke of Cambridge, on his recent visit to the UK for the Platinum Jubilee.
The revelations arose yesterday, with reports circulating that the rift between the once-inseparable brothers still remains.
The three Cambridge children did not meet their cousins Archie, three, and one-year-old Lilibet.
The Duke and Duchess of Sussex held a small private family party for Lilibet's first birthday, at Frogmore, inviting members of the Royal Family.

The couple invited Kate and William and their three children, Prince George, Princess Charlotte and Prince Louis, but the family did not attend, reports the New York Post.
The Cambridges shared their well wishes to Lilibet via Twitter post instead.
“The Sussexes left without spending any solo time with William, Kate and the mini Cambridges — and their kids, Archie, three, and Lili, didn’t get to see their cousins,” the newspaper claimed.
Kate and William visited Cardiff on Saturday for Jubilee celebrations, accompanied by two of their children Prince George and Princess Charlotte.
The family then travelled back to London to attend the Party at the Palace Jubilee Concert, accompanied by other members of the Royal Family.
Journalist Angela Levin, who spent a year with Harry while writing his biography claimed the royal is "absolutely furious" about being ignored on their recent trip to the UK.
Ms Levin alleged Harry didn't think to check brother William's diary before departing from his California home, with wife Meghan and children Lilibet, one, and Archie, three.
Her Majesty was introduced to her great-granddaughter on Thursday, following the Trooping the Colour ceremony, but the Queen is said to have refused to be photographed at their preliminary meeting.
The Duke and Duchess of Sussex flew back to their California home hours before the closing Pageant for the Jubilee celebrations began.
Upon landing in the US, photographers captured a pensive Harry gazing out of the window of a 4x4 car.
While Harry and Meghan were not awarded the same status as the working royals, they were given greater status than some minor royals.
They were chauffeured to the Service of Thanksgiving at St Paul’s Cathedral, while others such as the Tindalls arrived for the service in a bus.
At the service, Harry appeared to be more nervous of the two.
The Duchess of Sussex, in a Dior trench coat and matching hat, smiled as she walked through the cathedral, while Harry nervously bit his lip at times and nodded greetings to the congregation.
