Naomi Watts has crossed over to the dark side!
The blonde beauty debuted her darker 'do while filming, Diana, in London on Tuesday.
For this particular scene Watts, who plays Princess Diana, has a romantic encounter with her lover, Dr. Hasnat Khan, but to keep the relationship on the DL, she would dye her hair to throw off the paparazzi.
Not only is this making us more excited for the film, but we’re absolutely loving Naomi's newly dyed tresses.
