Friendly, creative, emotional and intellectually advanced? I don't think there is a problem there, other than dealing with a child that's not a perfect robot. She is most likely a gifted child, that's a good thing.
However, psychiatry might have a mental disorder for her, maybe some kind of Disney princess syndrome or DPS.
IMHO, Don't worry; she sounds like an exceptional child and will later learn better social/getting along with others skills as time goes on. But I'm not a doctor nor a member of the Walt Disney Co., so I'm not qualified to diagnois DPS
