Vanessa Feltz has suggested that Camilla is "keeping a lid on Charles' temper" ahead of the Coronation.
All eyes will be on the King, 74, and his wife, 75, on May 6 at Westminster Abbey.
Not everyone approves of Camilla - following her reported affair with Charles when he was married to Diana - however Vanessa, it seems, is a fan.
When responding to claims some of the older royalists disproved of the Queen Consort's relationship with the King, the TalkTV host, 61, told Alison Hammond and Dermot O'Leary on This Morning : "That's not fair, she keeps a lid on his temper.
"She made a speech at Gyles Brandreth's birthday and she was absolutely hilarious, I had real belly laughs!
"She's an authentic person. She's not trying to be someone she isn't."
Invitations for the Coronation were sent out to more than 2,000 guests and for the first time since Queen Elizabeth's death, Camilla was referred to as 'Queen' on the formal letters.
The invitations, which were publicly revealed yesterday, say: "The Coronation of Their Majesties King Charles III & Queen Camilla - By Command of the King the Earl Marshall is directed to invite... to be present at the Abbey Church of Westminster on the 6th day of May 2023."
A royal source told Sky News: "It made sense to refer to Her Majesty as the Queen Consort in the early months of His Majesty's reign, to distinguish from Her Majesty Queen Elizabeth II.
"Queen Camilla' is the appropriate title to set against 'King Charles' on the invitation. The coronation is an appropriate time to start using 'Queen Camilla' in an official capacity. All former Queen Consorts have been known as 'Queen' plus their first name."
It's still not known whether Harry and Meghan will attend the Coronation.
They have been invited, but their attendance seemingly rests on a number of factors, including their reported desire for a 'showdown' chat with Charles and Prince William and acknowledgement of Prince Archie's fourth birthday.
Relations between the Netflix stars and the Royal Family are at an all-time low, making the seating plan a potential headache for anyone to arrange.
At the Queen's funeral, Harry and Meghan sat directly behind Charles and Camilla, in the second row next to Princess Beatrice and her husband Edoardo Mapelli Mozzi.
Disgraced Prince Andrew got a front row seat along with his siblings - and there is an understanding that Charles will follow 'protocol' again.
Even though Harry, Meghan and Andrew are no longer working royals, past precedent is expected to be followed.
