Wow, since she has ZERO planets in Aquarius, I am puzzled. There is such a strong aquarian element to her, which imo cannot be explained by just having Venus Uranus trine, so I am going to go out on a limb and say that she is Aquarius rising, with her ascendant trining her Uranus and sextiling her Venus. T. Neptune would be currently going over her ascendant, bringing her glamour, worldwide notoriety, exposure and success. Plus T. Jupiter will soon be going over her ascendant too, so it's all gravy for her right now.
This ascendant would put her mercury in the first house, trining her moon in scorpio in her MC. That's a very good placement for a performer who wants to sing, write her own songs, and push sexual envelopes.
My second guess is that she is Virgo rising, with her ascendant SQUARING Uranus and quincunx Venus. This particular square could explain her extreme outlook, and the fact that her performances always look controlled and painstakenly rehearsed, even when she seems out of bound and crazy. She has this "wild perfectionistic Virgo" quality to her, which I suspect is one of the ancient forgotten archetypes of Virgo. You can see it in Madonna sometimes, and she also has Virgo rising. Virgo rising would give Gaga Chiron in dual Gemini at the MC, which could explain some of the rumors about her supposed hermaphrodism and would validate her claims of being bi-sexual. Well, Venus trine Uranus tends to like sexuality that is outside the norm anyway...
