Princess Kate reveals poignant reaction of her son Louis, 4, after she told him his great-gran The Queen had died

PRINCESS Kate revealed son Louis' poignant reaction after she told him the Queen had died, a well-wisher said.

The new Princess of Wales' four-year-old is said to have remarked: "At least granny is with great grandpa now."

And Kate was welling up when she told her three children of the news, mourner Banita Ranow, 28, said after speaking with her at Windsor Castle today.

Prince Louis had joined his siblings George, nine, and Charlotte, seven, for his first day at school this week.

Kate joined husband Prince William, along with Prince Harry and Meghan Markle to view tributes.

Ms Ranwo said it was "really nice" to see the brothers together.

Her mum Baljinder, 64, called it "fabulous", adding: "It was so beautiful to see."

She added: ";I felt so emotional and I felt the Queen would have loved it.

"I just hope in the future they remain like that and that the brothers come together, and the families."

Meghan Markle put a comforting arm around Prince Harry as they viewed tributes to The Queen.

The Duchess of Sussex also held his hand as they stepped out the car at Windsor Castle to greet crowds of mourners.

And Harry also put his hand around his wife in a separate moment this evening as they shared in the outpouring of grief.

They met crowds of mourners with Kate and William, speaking with them and collecting flowers from them.

One young child gave Prince William a small cuddly Paddington Bear. The children's character gave a touching tribute to the Queen on Thursday.

Meghan also smiled as she was handed several bouquets of flowers.

And in one moment a mourner embraced her in a long hug.

Meghan walked over to a section of the crowd and approached a teenager, who was seen putting her hand over her mouth in shock.

It comes as...

• Charles was today officially proclaimed King in a historic ceremony
• The Queen's funeral date was confirmed
• Prince William released a heart-warming tribute to his "grannie"
• Royals including Princess Eugenie were brought to tears as they looked at tributes left to the Queen in Scotland
• Meghan and Harry joined William and Kate to speak with mourners at Windsor
• The Duchess of Sussex hugged one young woman who gave her condolences

The pair spoke briefly for a few moments and Meghan could be seen assuring her by putting her hand on her shoulder.

The girl then said: "Can I have a hug?" and Meghan was seen nodding, before leaning in and giving her a big hug.

Prince William extended an olive branch to his brother by inviting him to view the tributes with him.

The invite is an indication William may be willing to forget their reported feud through the grief.

It comes after King Charles III yesterday expressed his "love" for Harry and Meghan in his first address to the nation.

And Prince William today paid tribute to his "grannie" the Queen, who he said was by his side during the happiest and saddest moments of his life.

He said: "On Thursday, the world lost an extraordinary leader, whose commitment to the country, the Realms and the Commonwealth was absolute.

"So much will be said in the days ahead about the meaning of her historic reign.

"I, however, have lost a grandmother. And while I will grieve her loss, I also feel incredibly grateful. I have had the benefit of The Queen’s wisdom and reassurance into my fifth decade.

"She was by my side at my happiest moments. And she was by my side during the saddest days of my life. I knew this day would come, but it will be some time before the reality of life without Grannie will truly feel real."

Other family members still at Balmoral Castle also viewed tributes to The Queen.

Heartbroken granddaughters Princess Eugenie and Zara Tindall broke down. Sophie, Countess of Wessex also appeared emotional.
