So, why the sudden switch-up? For starters, Brie only went blonde for a role in her husband Dave Franco's directorial debut film, The Rental . After the color transformation in April, Brie wrote on Instagram, "When your husband asks you to 'go blonde' for a role... you say yes." According to IMDb, the project is officially in post-production, which means Brie is off the hook, and apparently wasted no time in getting back to her roots.
