A delighted Prince Harry cracked out the 'dad jokes' alongside an amused Meghan yesterday when revealing their newborn son Archie Harrison Mountbatten-Windsor.

The Duke and Duchess of Sussex spoke at a photocall in the grounds of Windsor Castle ahead of a meeting with the Queen - the first member of the royal family to see the child since his birth on Monday.

When asked to expose more of their baby's face to the cameras, the Duchess laughed as Harry joked:

He’s already got a little bit of facial hair as well, wonderful.

As her husband held their son, Meghan said: ‘He has the sweetest temperament, he's really calm.’ To which a cheeky Harry replied: ‘I don't know who he gets that from,’ before sharing a knowing smirk with his wife.

Their baby boy will not have a royal title like Kate and Williams' children, Prince George, five, Princess Charlotte, four, and Prince Louis, one, but will be known simply as Master Archie after George V limited titles within the family during the First World War.

The child's name was revealed on the couple's Instagram account this afternoon, four hours after the beaming pair first showed their 7lbs 3oz (3.2kg) child to the world, during which Prince Harry described him as a 'little bundle of joy'.

It's believed that during the intervening period, the couple went to visit the Queen. With Meghan describing it as a 'nice moment to introduce the baby to more family.'

And in an image posted yesterday the Queen, who was also seen earlier at The Royal Windsor Horse Show, is seen happily smiling at the newborn alongside her husband Prince Philip.

Baby Archie, who was born at 5.26am on Monday, is also shown in the black and white image, alongside his grandmother Doria Ragland and parents Harry and Meghan - who has described her first few days of parenting as 'magic'.

Archie is the shortened version of Archibald, a traditionally Scottish name which is said to mean 'true, bold and brave'.

Unlike many senior royals, Archie only has one middle name - Harrison - which is of Aboriginal origin and, in a fitting tribute to the baby's father, means 'son of Henry' or 'son of Harry'.

Many in Britain had expected a more traditional royal name, with bookies favoring James, Arthur, and Edward, with Archie sitting at around 100/1.

Famous Archies include red-haired cartoon character Archie Andrews from the Archie comics franchise in America, as well as NFL quarterback Archie Manning.

Archie Mitchell was a villain in the BBC soap EastEnders, Lawrenece Olivier played Archie Rice in The Entertainer, and another famous Archie is jazz saxophonist Archie Shepp.

Harrison, meanwhile, has largely been made popular thanks to Star Wars actor Harrison Ford.

The couple did not disclose why they had chosen the informal names but Archie is becoming increasingly popular in Britain and was among the top 20 most common boy's names in 2017, according to the Office for National Statistics.

UK royal names are normally chosen from a relatively restricted pool of those used by past kings and queens.

But reports previously emerged that Meghan and Harry were considering an unusual name that was relevant to both Britain and the US.

Meghan also ignored tradition by keeping the birth and recovery process private, unlike sister-in-law Kate, who appeared before the cameras hours after giving birth.
