Transformation: Nicole Kidman heads to the Menton, France set of her new movie Grace of Monaco on Tuesday

Nicole, who is currently filming the movie in Menton, France, was styled in a pale yellow tent coat, strings of pearls adorning her collar.

Her cropped blonde locks were swept up into soft curls, mimicking the late Hollywood actress' famous hairstyle.

Accompanied by an assistant, Nicole was shielded from the sun by an umbrella on her way to set.

Assistants were later seen wrapping her locks in a polka-dot headscarf, and sliding winged sunglasses onto her face, making for a trademark look often worn by the late Hollywood star.

Grace of Monaco, which recently began lensing, tells the story of Grace Kelly's involvement with Monaco's Prince Rainier III and France's Charles De Gaulle dispute over tax laws in the early 1960s.

Grace of Monaco is scheduled for release in 2014.

Nicole recently opened up about the conflicting aspects of her personality, revealling toHarper's Bazaar she's only recently become more comfortable in front of the camera.

'I was shy. Deeply shy,' the Oscar-winning actress said of her early career, then married to Tom Cruise.

'I didnt feel comfortable at all. But I felt very comfortable at home.'

Things have changed somewhat, however, since she's moved on with her husband, country music star Keith Urban.

'All of that other stuff becomes less important [as you get older],' she said.

Nicole and Keith, who married in 2006, share two daughters, Sunday and Faith.

Keith was seen arriving in Nice, France, with the girls on Monday, taking them to visit their mom on set.

Keith schedule is now ramping up too thanks to his new job as a talent show judge with Mariah Carey, Nicki Minaj and Randy Jackson.

The country singer - who quit the Australian version of The Voice earlier this month -recently said he was 'so excited' to have landed the role.

Mike Darnell, President of Alternative Entertainment for Fox, believes the talent show has recruited one of the 'most exciting judging panels around' for the forthcoming season - which is due to air in January - after Nicki and Keith replaced outgoing judges Jennifer Lopez and Steven Tyler.

He said in a statement: 'Nicki's an unbelievably captivating international phenomenon who has made an indelible mark on rap and pop.

'Keith is another great addition to 'Idol' - he's one of the biggest stars in country music and I know that our fans and contestants will fall in love with him.

'With an unparalleled star like Mariah, fan-favourite Randy, chart-toppers like Nicki and Keith and our incomparable host Ryan, we've put together one of the most exciting judging panels around.'

Randy - who has been a judge on the programme since it began in 2002 - signed a new deal to remain on the show after talks with Spanish singer Enrique Iglesias broke down.

But X Factor judge Simon Cowell - who was a panellist on 'American Idol' from 2002 to 2010 - has insisted keeping Randy on is the 'right decision'.

He tweeted: 'Just heard Randy is back on Idol. Right decision.'
