THE Queen’s hilarious joke about Princess Anne’s kids has been revealed in an explosive new book.
Prince Philip's friend Gyles Brandreth has spoken about Her Majesty’s sparkling wit during her daughter’s wedding to Mark Philips.
The horse-mad pair wed in 1973 in a beautiful royal wedding in Westminster Abbey.
The Queen's only daughter won three European Championship medals and even went to Olympics in Montreal in 1976.
Meanwhile Philips was also a gold-winning olympian - which lead to the Queen’s hilarious joke.
The upcoming biography called Elizabeth: An Intimate Portrait says Her Majesty made a quip about the couple’s future children.
During their marriage, Princess Anne had two children with Mark - Peter and Zara.
After Zara's birth, Princess Anne and Mark were rumored to have marital troubles, after they were rarely seen together.
The couple separated in 1989, and divorced each other in 1992.
Later that same year, Princess Anne tied the knot with Timothy Laurence.
It comes after it was revealed the Queen secretly fought painful cancer in the final year of her life.
Her late Majesty is said to have had a form of bone marrow cancer, which symptoms include bone pain, before her death on September 8.
Her death certificate, released in September, officially recorded her cause of death as "old age".
But Mr Brandreth wrote: "I had heard that the Queen had a form of myeloma — bone marrow cancer — which would explain her tiredness and weight loss and those ‘mobility issues’ we were often told about during the last year or so of her life.
