Princess Diana is bringing her boys together as they reportedly put aside their reported differences to keep their traditional gathering to mark the anniversary of her death.

Hello magazine reports that Princes William and Harry spent the morning together sharing stories of their mother and looking at old photographs on the 22nd anniversary of her passing.

The boys were just 15 and 12 respectively when Diana, Princess of Wales, was killed aged 36 in a Paris car crash.

United in grief, the princes have reportedly grown distant from each other this year amid reports of a rift that saw Harry and his wife Meghan move away from their home in Kensington Palace near William and Kate and into Frogmore Cottage at Windsor 34km away.

However, Hello magazine says they kept their annual meeting and hung out alone before being joined by their wives Meghan and Kate as well as their children in the afternoon.

"They talk about the little things about Diana that made them laugh: the ski trips and outings to Thorpe Park; the effort she went to on their birthdays — all of it.

"Their other halves and kids join them later," a source told the magazine.

Royal devotees have gathered outside Kensington Palace to mark the 22nd anniversary of Diana's death.

Pictures show members of the public sitting outside the Palace in Hyde Park, London, her former home that is now used by William and Kate, with pictures of Diana.
