ITV's Chris Ship was overwhelmed as he got used to saying the words 'His Majesty the King'.
The broadcaster was reading a statement from Prince Charles, who is now the King, and referred to him as 'His Majesty the Queen' before fixing his error.
Chris read the statement regarding Queen Elizabeth II's death : "The death of my beloved Mother, Her Majesty The Queen, is a moment of the greatest sadness for me and all members of my family,” the statement read.
"We mourn profoundly the passing of a cherished Sovereign and a much-loved Mother. I know her loss will be deeply felt throughout the country, the Realms, and the Commonwealth, and by countless people around the world.
"During this period of mourning and change, my family and I will be comforted and sustained by our knowledge of the respect and deep affection in which The Queen was so widely held."
He then said the statement was from 'His Majesty the Queen' again.
"Sorry, a statement from His Majesty the King," he corrected himself before he mentioned that even people following the story for a long time can 'make those mistakes'.
He repeated the mistake one more time, before being corrected, and adding: "As difficult as it might be to roll off the tongue."
Clarence House has confirmed the new King will officially be known as King Charles III.
Charles, who was born on November 14, 1948, is the eldest of the Queen and Prince Phillip's four children.
He was said to have been closer than ever to the Queen in the months leading up to her death.
Buckingham Palace made the announcement of the Queen's death at 6.30pm, stating: "The Queen died peacefully at Balmoral this afternoon. The King and The Queen Consort will remain at Balmoral this evening and will return to London tomorrow."
The new Prime Minister, Liz Truss, made a statement outside Downing Street and described the devastation felt across the country at her passing after a lifetime of service.

She said: "Queen Elizabeth II was the rock on which our country was built.
"Britain is the great country it is today because of her."
The PM described the Queen as the "very spirit of Great Britain" and promised: "That spirit will endure."
Speaking on only her third day in office, Ms Truss recalled meeting the Queen on Tuesday when she invited her to form a Government in her name.
The PM said: "She has been a personal inspiration to me and to many Britons. Her devotion to duty is an example to us all.
"Earlier this week, at 96, she remained determined to carry out her duties as she appointed me as her 15th Prime Minister."
