The 24-year-old actress was spotted with a darker new 'do on Monday, according to E! Online. With production on Fifty Shades slated to begin in just three weeks, it comes as no surprise that Johnson has changed her hair to match that of her character Anastasia Steele.
Johnson, the daughter of Melanie Griffith and Don Johnson, was cast as Anastasia Steele back in September. Johnson will star opposite Once Upon a Time alum Jamie Dornan, who replaced Sons of Anarchy's Charlie Hunnam.
Fifty Shades of Grey is slated to hit theaters on Aug. 1, 2014. What do you think of Johnson's hair?
