Every stanbase of any successfull pop acts call their fave Queen of Pop. But that doesn't mean they actually believe that she is the queen.
For better or worse Madonna IS the Queen of Pop. That can't be denied. But Britney is sometimes call that because at some point in her career, she shakes the pop world in a sense that only Madonna managed to do.
And this won't end well...
