The source told The Sun: "Her Majesty wanted to formally welcome the Sussexes to their new home so she was their first visitor.

"After all, they've practically moved into her back garden. She visited with other family members and Harry and Meghan were delighted to show them round."

News of Her Majesty's visit sparked some speculation on Twitter that the Queen's newest great grandchild had already arrived.

Also welcomed at Frogmore Cottage by the expectant couple have been the Duke and Duchess of Cambridge, Princess Anne's daughter Zara and husband Mike Tindall.
