NO. Why is Elle Fanning growing up so fast!?!

13 year-old Elle Fanning looks a bit more mature in an age appropriate white dress cut-out dress by Louis Vuitton Spring 2012 collection and a pair of silver heels also by Louis Vuitton at the “We Bought a Zoo” premiere held at the Ziegfeld Theater in New York City on Monday (December 12)- more pictures below.

Dakota Fanning’s sister would have looked perfect if she had not worn those heels, which seem totally out of place when in combination with that super cute, youthful dress.

Elle, don’t you ever dare to stop being cute!

“We Bought A Zoo” hits theaters on December 23, 2011.
