SHE is known for her unflappable manner during political television coverage.
But Laura Kuenssberg was forced to apologise on air when she failed to call Kate Middleton by her correct title.
The BBC News' Political Editor used the royal mum-of-three's maiden name rather than the Duchess of Cambridge.
Speaking on podcast Brexitcast, the respected broadcast journalist made the blunder when discussing how the last two remaining Tory leadership candidates, Boris Johnson and Jeremy Hunt, will have to act as 'quasi Prime Minister' until one of them is picked to replace Theresa May.
She said: “Imagine if Johanna Konta gets to the final round of the Wimbledon ladies final.
“They will be begging for tickets in the Royal Box.
“Who is going to sit next to Kate Middleton?
“Oh my goodness, will it be Boris on one side and Jeremy on the other?”
However, the BBC's Brussels foreign correspondent was quick to point out Kuenssberg's mistake.
She apologised immediately.
It comes as Prince Harry and Meghan Markle's royal matchmaker has found love with a restaurant manager.
They revealed in a BBC interview in 2017, on the day they announced they were to wed, that they had been "set-up" by a "mutual friend" - and now she is set to walk down the aisle herself.
The Duke and Duchess of Sussex, who recently welcomed baby son Archie Harrison, went on a blind date in early July 2016.
Now, Violet von Westenholz - who attended the couple's 2018 wedding - is dating Archie Seymour, 30, the openings manager at restaurant Chotto Matte in London’s Soho.
