Dark locks look pretty good on Naomi Watts.
The actress, who is portraying the late Princess Diana, showed off the new 'do while on the Diana set in London today.
The dramatic transformation was for a scene showing Princess Di's romantic meeting with Hasnat Khan (Naveen Andrews), a doctor whom the royal was secretly dating.
And that's where the brown hair comes in.
In order to keep the relationship discreet, Diana would change hair color to throw off all the paparazzi around her.
We know this is all part of the job, but maybe Watts should consider keeping this look after the film wraps?
