Princess Nicole!

Nicole Kidman continued morphing into the late Grace Kelly shooting biopic Grace of Monaco aboard a yacht in St. Barts on Tuesday, Oct. 23. In one of her most stunning recreations yet, the 45-year-old actress wore her strawberry blonde hair in a dramatic, braided updo, clad in a gold gown and wrapped in a fur shawl.

The real Princess Grace of Monaco wore the look first in an iconic look from 1963. The American-born Rear Window actress Kelly wed Prince Rainier of Monaco in 1956; after bearing four children, she passed away in a car crash in 1982 at age 52.

Costarring Tim Roth as Prince Rainier, Grace of Monaco centers on Kelly's involvement with her adopted country's dispute with France's Charles de Gaulle over tax laws.

When overseas shooting wraps for the film, Kidman hopes to take a little R&R -- hanging out backstage as husband Keith Urban judges American Idol alongside fellow newbies Mariah Carey and Nicki Minaj, plus veteran Randy Jackson.

"Next year I'll be there," Kidman said at the Emmys last month. "This year I'm in France, playing Grace Kelly."
