Rumours have continued to swirl about the family’s dynamic, despite notable public appearances showing the royals laughing and smiling together.
Kate and Meghan showed their support individually at the Wimbledon tennis championships this week, but the former was present with her husband at baby Archie Harrison Mountbatten-Windsor’s Christening.
“She didn’t do that,” Piers noted first, and Tatum nodded emphatically.
“Exactly!” she exclaimed. “I think she gets it, I think Kate really gets it.
“She gets the lack of privacy and I hope that they’re not fighting, I hope not.”
At that, Piers couldn’t resist sharing some insider information and sadly burst the guest’s bubble over happy family unions.
“I hear bad rumblings I’ve got to say,” Piers continued. “Between the Sussexes and Cambridges.”
“So do we here in America,” Tatum chimed in.
“I’m told from people who are in there that there’s a real problem, there is a problem,” Piers then insisted.
“Can you imagine though? It seems to me that they could not be nicer people,” Tate responded with a laugh. “Like how do you not get on with Kate and William, like how?”
“I think Meghan has certainly put a firecracker up the royals and I’m not sure that all of them like it very much,” the host said finally.
The ITV programme also featured an appearance from former BBC sports reporter Sally Jones today, who was the one who claimed she was told not to take pictures of the Duchess.
Explaining what happened, she told Piers and his co-host Susanna Reid: “I’m a great fan of the royals… Two days earlier the Duchess of Cambridge had also been watching, also from that court, no fuss.
“It all seemed to be part of that business about the secrecy over the godparents and trying to prevent the media getting any kind of handle on…
“And that business of one moment you are told Meghan has gone into labour and a few minutes later you are told the baby was born a few hours ago.
“You almost feel the media and the public, who really love that couple, are really being taken for mugs,” Sally added.
Yesterday’s show saw a frustrated Piers tell the Duchess to “go back to America”, prompting immense backlash from fans.
