I just google-imaged

She does have this weird bobble-head look going on. Like, at certain angles, her head seems like it's not fastened onto her neck in the usual sense. Like a doll. Wouldn't say it is particularly big though.

As far as hotness factor(sheesh...have I been reduced to this?) goes, if she were not completely opposite my type I could give a more un-biased opinion.

Though if those are recent pics that came up first, I too am shocked she is thirteen! Physical arrested development rocks!
