Buckingham Palace announced on Thursday, 8 September that Queen Elizabeth had died at the age of 96, following a 70-year reign.
As a result, her eldest son will officially take over, making him King Charles III.
As well as Charles and Camilla's new titles, Prince William, who was the Duke of Cambridge, is now the Duke of Cornwall and Cambridge and is expected to become the Prince of Wales after Charles' coronation.
Meanwhile, although Prince Harry and Meghan Markle's titles will remain the Duke and Duchess of Sussex, their children will be given titles of Prince Archie Mountbatten-Windsor and Princess Lilibet Mountbatten-Windsor.
While William and Harry's children will get new titles, Camilla's will not.
Before she married Charles, Camilla had two children with her first husband Andrew Parker Bowles.
Her son Tom Parker Bowles, 47, works as a restaurant critic and food writer, and shares two children with his ex-wife Sara Buys.
And Camilla's daughter Laura Lopes, 44, is an art curator who shares three children with her husband Harry Lopes.
Since Camilla's title depends on Charles', she cannot pass on any royal titles to her children, meaning that neither Tom or Laura will get new names.
As the Queen Consort, rather than the Queen, Camilla doesn't hold the same type of power that Queen Elizabeth II held.
And when Charles eventually leaves the throne, and his son William takes over, Camilla will lose her title.
Queen Elizabeth announced back in February that Camilla would one day hold the title of Queen Consort.
In a statement issued at the time, she announced: "When, in the fullness of time, my son Charles becomes King, I know you will give him and his wife Camilla the same support you have given me.
"And it is my sincere wish that, when the time comes, Camilla will be known as Queen Consort as she continues her own loyal service."
Queen Consort is the same title that was given to the Queen Mother - the wife of King George VI - before he passed away.
Camilla's new title was confirmed by the Palace in the announcement of the Queen's death on Thursday evening.
It read: "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."
