PRINCE Archie, 4, and Princess Lilibet, 2, recorded adorable special birthday messages for their “grandpa Wales” after he turned 75.
The two young royals were said to have “delighted” King Charles on his special day after filming themselves singing happy birthday.
Their father Prince Harry, 39, made headlines after he broke his silence to ring his father and wish him happy birthday.
The gracious monarch was also understood to have spoken with his daughter-in-law Meghan during the transatlantic call.
The chats were said to be friendly and cordial — the first time father and son had spoken since April, just before Charles’s Coronation.
And the fact that they have signalled a desire to bury the hatchet and start to mend their relationship was hailed a positive sign that was celebrated on both sides of the Atlantic.
A source said: “The King was extremely busy but is polite and loves his son and his grandchildren, and not so mean that he would not take a call on his birthday.”
The Sun also understands that during Monday’s conversation, Harry, Meghan and Charles made plans for them to speak again soon.
Despite visiting the UK several times since the Coronation, the Duke of Sussex has not seen his father since that historic day in May.
They have not spoken face to face since Queen Elizabeth’s funeral in September last year and it is known the King has previously been reluctant to take Harry’s calls following rows over Megxit and his money.
Queen Camilla and Prince William have also been urging the King not to engage with Harry after he blasted the Royal Family and the UK on Netflix and in his memoir Spare.
But Charles was said to be keeping the door open for his “dear boy” and there is an open invite to meet when he is in the UK.
Our source added: “There is still a long way to go to mend the rift created over many years — and the deeper issues caused by allegations in the Netflix series and Spare are not healed with a phone call.”
Charles had insisted his birthday would be a “normal working day”.
He chose to spend it helping those suffering from food poverty and to recognise the heroic efforts of the NHS staff and midwives.
The monarch was full of smiles when he was joined by Camilla in Didcot, Oxon, to launch his much-heralded Coronation Food Project, which aims to end food waste.
And he laughed nervously as he was treated to a rendition of Happy Birthday at the South Oxford Food and Education Alliance.
The project was devised by the King amid shock over food waste and the cost of living crisis.
Inside the hub’s offices, Charles and Camilla popped into the kitchen where chef Alex Mackay and a team of volunteers were making hot dishes from leftover food.
The King chatted to food “influencers”, including 2021 Bake Off runner-up Crystelle Pereira, and the chief execs of several major supermarkets and food suppliers.
