Karl Stefanovic's brutal joke about Harry and Meghan's baby name

Karl Stefanovic has mocked Prince Harry and Meghan Markle's unique baby name for their daughter, Lilibet 'Lili' Diana Mountbatten-Windsor.

During an interview with Piers Morgan, Today host Karl made it clear he wasn't a huge fan of the name, asking the controversial host: "What did you make of the name Lilibet? Does it sound like a sports betting app?"

Australia does have a number of betting apps that one could argue sound similar to Lilibet such as Unibet, Sportsbet and Pointsbet.

The name, however, was inspired by the Queen's family nickname that came about because she was unable to pronounce Elizabeth as a young girl, instead saying Lilibet.

Her grandfather King George V began calling her Lilibet and the name stuck. The late Prince Philip is also known to have lovingly referred to the Queen as Lilibet, telling his mother-in-law after their wedding, "Lilibet is the only 'thing' in the world which is absolutely real to me."

Piers responded by blasting Harry and Meghan for using the Queen's nickname, despite spending the last few weeks "trashing the royal family and the monarchy".

"I think it's quite ironic, isn't it?" he said. "You have this couple who have been trashing the royal family and the monarchy for the last few weeks and they have named the baby after the Queen."

It's believed this tribute to the Queen by the Sussexes will be seen as an olive branch.

"Maybe it's their way of reaching out, as the Americans say, to the royals and wanting some kind of end to this on-running feud," Piers added.

"I always think when a new baby is born, I've had four myself it's churlish to put any negative slant," he said. "At such a moment. I wish them all the very best. There is four in the family now. I wish them every success and a long and happy life."

Lili is eighth in line to the throne and was born in Santa Barbara Cottage Hospital in California.

Royal author and journalist Omid Scobie tweeted that the couple will "not be sharing a photograph at this time" and that they're now on "parental leave".

Meghan and Harry's bombshell interview moments

Meghan and Harry shocked the world when their bombshell interview with Oprah Winfrey aired earlier this year with the pair claiming an unnamed senior royal made remarks about the colour of their son Archie's skin colour.

The pair didn't stop there, with Harry later telling Oprah he was left alone to deal with the press storm following Princess Diana's death, saying Prince Charles' advice to his sons was to resign themselves to "suffering".

"My father used to say to me when I was younger, he used to say to both William and I, 'Well it was like that for me so it’s going to be like that for you,'" Harry said.

"That doesn’t make sense. Just because you suffered doesn’t mean that your kids have to suffer, in fact, quite the opposite - if you suffered, do everything you can to make sure that whatever negative experiences you had, that you can make it right for your kids."
