Update: Turns out Dakota didn't exactly take the pixie plunge. The new style is actually a wig, confirmed her reps to People.
Previously: Perhaps channeling Mia Farrow and Emma Watson, Dakota Fanning debuted a pixie cut on Monday while on set for her latest film, "Now Is Good," and BauerGriffin has the photos.
While the actress likely ditched her blonde locks for the movie in which she plays a leukemia patient, the style would be chic enough to maintain once filming wraps.
