Nicole Kidman has been immortilised in wax.

The Australian actress is the star of a new exhibit at Madame Tussauds’ waxwork museum - and it's a pretty good likeness.

The figure took four months to make, and shows Kidman - currently in Sydney with husband Keith Urban and new daughter Sunday Rose - in a crimson gown.

A spokesperson told Now magazine the figure showed off Kidman's "flawless beauty".

"Nicole is wearing a stunning floor-length red dress which really emphasises her flawless beauty and grace, idolised by so many women around the world.

"There’s no mistaking that she is a hugely popular global celebrity, and we are delighted to be unveiling her today."

The waxwork is part of Madame Tussauds new winter wonderland exhibit, with Kidman placed in a snow scene complete with Christmas tree.

A waxwork figure of troubled soul singer Amy Winehouse was unveiled last month.
