I love her hair and ponytail too, it's so thick and a lovely color. She is cute as a button to boot.
Love seeing her in concert, with her hair all bouncy while she's performing and looking so hot.
She almost always wears her hair in a ponytail, or rather, a "half" ponytail ie where only part of her hair is tied. I wish she would wear it all down more often - great hair for sure!
