I know so little about her, and have never really thought about her type, but ISFJ would be plausible based on what I have distilled from her when I've seen her act. (Not the roles she has played... but rather how she approaches them.)
Yes, she is indeed, isn't she? I really like her personality. She has a soft voice and lots of grace. She seems to epitomize feminity at is finest: sensitivity, strength and wisdom.
