I don't know enough about her to type her for certain, but I do remember an interview where she explains why she has created the visual image of herself as it is. She said that as a little girl she saw some women in her home town who looked so beautiful to her, and they had the boob job, bleached blonde hair, heavy makeup, etc. She admired them so highly that she copied the look for herself. That particular, fundamental motivation makes me think she could have Si because she internalized that archetype of how a woman should ideally look. Her vibe feels Fe to me, but I'm not sure. If I had to say one, it might be ESFJ. I think she is determined and motivated.
Edit: Actually, if I remember correctly, I think she describes herself as having a good head for business. I'll try to look that up to verify. It is easy to assume she isn't "T" because she has such an extremely feminine look, but I'd be curious to hear any reasons why she is defined as "F" over "T" or vice versa.
