The Queen rolled her eyes this evening when Prince Charles called her 'Mummy' when he took to the stage at the end of her birthday concert.
The Prince of Wales raised three cheers at the Royal Albert Hall when he wished his mother a happy 92nd birthday as a star-studded celebration came to a close.
Addressing the Queen, he first referred to her as 'Your Majesty', before switching to the more familiar "Mummy", prompting the monarch to roll her eyes and smile, reports Daily Mail.
They appeared on stage at the conclusion of the evening, flanked by performers on an evening which saw a spectacular line-up of singers including Sting and Shaggy, Tom Jones and Kylie Minogue.
Charles told his mother: "I have a feeling that in 1948 when you were 22, you didn't somehow expect at your 92nd birthday to find your son in his 70th year - just able still to raise a small Hip, Hip.
"Would you all give Her Majesty three unbelievably rousing cheers on her birthday?"
The audience responded rousingly, with the Queen waving her hand to acknowledge the warm applause.
The Queen took her seat at the Albert Hall wearing gold, while Prince Charles, the Duchess of Cornwall and Prince William joined her in the Royal box as the concert got underway.
She was then presented with a bouquet of flowers by seven-year-old Mason, who was also celebrating his birthday today.
Prince Harry also took to the stage during the concert to wish his grandmother a happy birthday, and said: "Tonight we are celebrating the Queen's Birthday but Your Majesty, if you do not mind me saying, you are not someone who is easy to buy gifts for."
Harry paid tribute to his mother and spoke about the charity work of the Queen's Commonwealth Trust of which he was recently appointed president.
Earlier in the day, honorary gun salutes were staged at Hyde Park, the Tower of London, a castle in Wales and the town of Windsor to mark the occasion.
The queen celebrates two birthdays every year: Her actual birthday on April 21, which she usually marks privately with her family, and her 'official birthday' in the summer. That usually falls on the second Saturday in June, when she joins the Trooping the Color military parade in central London.
Elizabeth's official birthday this year came on the tails of the Commonwealth Heads of Government meeting, which brought the leaders of the 53 Commonwealth countries together in England.
The queen has led the disparate group, made up of Britain and its former colonies, since she took the throne in 1952.
At a meeting of Commonwealth heads of government this week it was agreed that Prince Charles would succeed the Queen in the role of head of the body.
