The Queen's Platinum Jubilee celebrations this weekend could see Prince William reunite with his younger brother Prince Harry.
The pairs rift has gone from bad to worse since Harry quit as a senior working royal with wife Meghan Markle and moved to the United States.
The brother's frosty relationship was reportedly sparked by William's concerns over Harry's fast-developing relationship with Meghan ahead of their royal wedding in 2018.
The tense row quickly boiled over - with Harry claiming his brother was "trapped" within the royal system during a bombshell interview with Oprah Winfrey.
Since leaving the UK in early 2020, Harry has only seen his brother twice - at the funeral of Prince Philip and at an unveiling of a statue of their late mother Princess Diana.
However, reports this weekend have suggested the brothers may be keen to their relationship back on track. So what signs have there been that show this could be a possibility?
FaceTime calls
The biggest sign yet that the brothers are ready to bury the hatchet was revealed by the Sunday People.
It reported that William and Harry are healing their feud with weekly online messages and face-to-face video chats.
The brothers have been messaging each other every few days on WhatsApp – and are also having regular FaceTime calls with their children.
But wives Meghan and Kate, both 40, have so far held back from onscreen contact, giving their husbands time to fix their relationship one-to-one.
William keen to move on
Meanwhile, the same Sunday People report says William had been disappointed about the abrupt way Harry and Meghan left the royal family and moved to California – but that he has now moved on.
A source said: “The brothers needed time for everything to settle down. The family, including William, had been disappointed in the way Harry and Meghan chose to leave the royal family.
"But now there is a strong feeling that what happened is in the past and that they have moved on.
“William sees that Meghan is a good mother and loyal wife and he is genuinely pleased for his brother."
Harry's trip to UK
Another sign that Harry is also keen to repair their relationship is h is decision to come to the UK with Meghan and their children Archie and Lilibet for the Jubilee celebrations later this week.
The family of four are due to arrive in Britain very soon and it could be that over the weekend, William meets his niece Lilibet for the first time.
It could be argued that if relations between the two brothers were so bad, Harry would not want to come to the UK for the Jubilee.
William's heartwarming comment
Even though their relationship is said to be rocky, it appears that William still speaks fondly of his younger brother.
In March while William and Kate were in Belize on their tour of the Caribbean, William was reportedly asked about Harry's previous trip to the country in 2012 - when he also showed off his dance moves.
Cynthia Ellis-Topsy, ambassador at large for the Garifuna nation, told PEOPLE magazine : "I said to William that when [his brother] Prince Harry came to Belize he was dancing and didn't need encouragement. He is a wild card.
"William laughed and said, 'Harry's not self-conscious'."
Kate's secret message?
Meanwhile, it may not just be William and Harry showing signs of a truce, has Kate also sent a secret sign that she's keen for the brothers to put their differences aside.
Last week, she wore a beautiful mint green dress with a hat in a matching colour at a Buckingham Palace garden party last week.
And some royals fans are convinced the hat was a direct tribute to Harry and Meghan as she wore an almost identical hat, only in a different colour, at the couple's wedding four years ago.
