Naomi Watts just got a royal makeover!
The British-born actress -- who moved to Australia in her teens -- was spotted on set of her latest film today, where she was seen in costume as Princess Diana for the first time.
Watts, 43, is currently filming "Caught In Flight," a movie about the final two years of Princess Diana's life.
With the short blonde hair, glamorous gown and pearl necklace, Watts is doing a pretty good job transforming into Diana, isn't she?
