A shake-up of the way the British Royal Family works could make it much easier for royal daughters to be crowned queen in the future.
The government wants to update Royal rules that haven't changed for hundreds of years, including one that makes the eldest son first in line to the throne.
Prime Minister Gordon Brown says female royals should have the same rights to the throne as males.
Talks about the changes are said to be ongoing with Buckingham Palace.
But getting them approved is likely to take a long time.
Prince Charles will still be next in line to the throne followed by William and Harry
That's because the British monarch is also head of state for 15 other Commonwealth countries, and they would also need to support the changes.
Whatever happens, it's unlikely to make much difference in the immediate future of the British monarchy.
As both the Queen's first child and eldest son, Prince Charles will still be next in line to the throne, followed by his sons, Princes William and Harry.
But it could impact on future generations if Prince William becomes king and has a daughter.
Under the current rules, she cannot be queen if she has a younger brother, but if the rules change she can.
