Dakota Fanning Goes Brunette!

Runaways actress ditched her trademark blond hair for pink in January; now she goes all the way brown

Dakota Fanning has officially crossed over to the dark side.

Yes, the 18-year-old actress and NYU student has traded in her trademark blond tresses for brunette (or as Lady Gaga would say, "Louis Vuitton brown") locks!

Dakota showed off her new hue on Instagram over the weekend, writing, "Well look who turned into a brunette!"

The natural blonde, however, is no stranger to experimenting with her hair color. In January, the Runaways star dyed the tips of her hair hot pink.

Which is your favorite of Dakota's hairdos?
