With a sidereal zodiac used she has her Moon in Leo and Sun on border of Cancer-Leo. From all her persona, her expressions and the fact that she has been "queen of pop" for decades, that surely describes a person who is not unlikely very much a Leo. So with her 7.05 chart that would all be true by sidereal chart.
It is probably possible for someone very capable to rectify her chart, but this might just be her right chart. If someone rectified her chart to an Aquarius ASC many years back, that just means that her angles are within LEO-AQUARIUS... it does not tell us which angle.
We know she lost her mother at a very young age, I think she was 6-7 yrs of age. That would most probably show us Saturn or Pluto symbolism on angles in pr. solar arc or sidereal solar return.
We know that she became famous at a very young age and became a star and it was not 15 minutes of fame (like a progr. angle passing by the Sun) ... it is long lasting fame. That could be a Sun on ASC or close to it. She is very self absorbed, self occupied - which is also a Sun quality/expression.
We know that she was raped when she had just arrived in NYC, I think she was 19-20 yrs at the time. That could be a sidereal solar return with Mars on angle, or it could be a progressed or solar arc Mars to angle.
We also know that she got married twice - those timings should show us either Venus or Jupiter or both on angles in progressed, solar arc or solar return....sometimes also a Moon-Uranus symbolism because it is a time of excitement for many.
We know she has received awards and we will probably see Jupiter symbolism to her MC for those types of events.
