Dakota Fanning sister

Did you know Dakota have a sister?
I discovered it a month after War of the Worlds .
I think, they are divine siblings.
From Elle I saw only Super 8 (great film).
I thought about it. How is this possible? Two sisters, two great actress. 
It is about their parents? Or they are both ultrataleted? Once I will ask Dakota.

Dakota Fanning with her sister Elle Fanning. Photo from young. Are not they amazing?

 
Elle is only 14 and she is taller than Dakota :).
I like Elle Fanning, she is good looking, but Dakota is much better. (Dakota is the best).
