Dakota Fanning and little sister, Elle Fanning.
The two look so much alike it's hard to tell them apart. Elle is staring in the newest Sofia Coppola film, Somewhere, in theaters now. In late 2010, it was announced that Dakota would not be taking on any new roles until she finished high school in 2011 (love wiki). It appears we'll be seeing a great deal of the Fanning sisters in years to come. They're not only incredibly talented, but stylish little models as well.
