Nicole Kidman stunned onlookers with her bony frame while out on promotional duties for her new film Australia. 

The actress - who gave birth to daughter Sunday Rose in July - has ditched the baby weight and then some judging by her non-existent bosom and protruding collarbone.

Nicole joined Australia co-stars including Hugh Jackman and director Baz Lurhmann at a press conference at the Museum of Contemporary ahead of the movie's world premiere in Sydney.

And with her scrawny arms and minuscule waist, Nicole seems to be shrinking to a unhealthy size zero.

Has she taken the post-pregnany dieting too far?
