Her voice is awesome , I like her too and I don't doubt that she may not do anything to be so skinny , I used to be like that and no matter what I did , I wouldn't gain an ounce, it's all about genetics I guess.
I also did think in the beginning that she acted like she was the only one who ever had a child but looking back so did I, and I don't think there's anyone in this earth who didn't feel like that with their first child unless they really don't want the child.
But I still don't like her hair now, maybe because I'm not used to see her with short hair.
