Naomi Watts' days as royalty are numbered as she continues to film the Princess Diana biopic Caught In Flight.
The actress has been working hard on the role all summer and wasn't slowing down this week in England.
Check out more pics from the Hertfordshire and Sussex sets which feature Watts all dolled up as she makes a fake public appearance….and then a little more relaxed while acting alongside co-star Naveen Andrews.
The Lost actor plays Lady Di's former lover, Dr. Hasnat Khan.
Ugh! The movie hasn't even wrapped yet and we're already holding back tears!
