Prince Harry and Meghan Markle reportedly spent only a quarter-of-an-hour with the Queen, when they came back to the UK for the Platinum Jubilee celebrations.
The Sussexes' meeting with Her Majesty was kept "formal" by Buckingham Palace aides.
The world's second-longest serving monarch met Harry and Meghan's one-year-old daughter Lilibet for the very first time.
Archie, who is now three, joined his mum, dad and baby sister for the visit at Windsor on June 2.
The California-based couple returned to the US on Sunday, before the Jubilee celebrations were complete.
Whereas the Duke and Duchess of Cambridge joined the Queen, Prince Charles, Lady Camilla, Prince George, Princess Charlotte and Prince Louis, on the balcony of Buckingham Palace.
The Sun reported that the Sussexes' meeting with the Queen was kept very brief, quoting a source as saying: "It was a quick in and out job. It was all quite formal."
Meanwhile, the Duke and Duchess of Cambridge are reportedly set for a move to Windsor.
The couple are said to be moving to a house on the Queen’s Windsor estate this summer.
William and Kate will keep Kensington Palace as their family’s London home, and continue to visit their Norfolk home, Anmer Hall, according to the Sunday Times.
Kensington Palace declined to comment.
It is also understood that the Cambridges have hired a new communications secretary, Lee Thompson, who is currently vice-president of global communications and strategic partnerships at NBC Universal.
Earlier this year it was reported that William is keen to do things “the Cambridge way”, following his Caribbean tour with Kate, which saw the couple heavily criticised for images that smacked of “colonialism”.
