Prince George and Princess Charlotte's new surname has been confirmed on the order of service for their great-grandmother's funeral on Monday.
As the children, who walked behind their parents the Prince and Princess of Wales as the Queen's coffin made its way from Westminster Hall, it was reported that they were now to be known as Wales instead of Cambridge.
As Prince William and Kate Middleton were formerly known as the Duke and Duchess of Cambridge, their children's name has changed to match theirs, confirmed during the state funeral and committal service, reports The Scottish Sun.

Now, at school, they are to be known as George and Charlotte Wales. Their younger brother, Prince Louis, who was absent from the funeral being just four-years-old, will also adopt the same surname.
Speaking previously to Australia's Sunrise TV show, royal expert Angela Mollard explained: "This must have been an enormous few days for Catherine.
"She's taken on a new role herself, but she's also got to teach her very young children. aged nine, seven and four, that their surnames have changed.
"They are no longer George, Charlotte and Louis Cambridge, they are now George, Charlotte and Louis Wales.
"Any parent will recognise that when you've taught a young child how to spell their name, that's the name they're knowing to among their classmates."
The Queen's coffin was on the move in a Gun Carriage earlier on Monday after Lying-in-State at Westminster Hall for four days, where tens of thousands of mourners queued all through the night to catch a closer look.
Her Majesty's funeral procession was led by King Charles III and Camilla, Queen Consort. The Queen's other three siblings were also present, alongside Harry and William.
Meanwhile, other members of the family who were not in the first procession — including George and Charlotte — joined at the door of the Abbey. Charlotte walked behind her mum and in front of Meghan.
She was supported by her big brother on her right, who was behind his dad and ahead of his uncle Harry.
