Nicole Kidman looked sensational as she arrived at the Glamour Of The Year Awards in New York City last night. 

Just four months after giving birth to daughter Sunday Rose, the actress looked flawless in a classic white floor-length dress, which showed off her svelte - yet womanly - figure.

But it seems the stress of motherhood has already given the Australia star a few extra grey hairs.

Nicole was sporting some silver roots on her normally immaculate strawberry blonde hair.

The Oscar-winning star picked up an award for her efforts as a Goodwill Ambassador for UNIFEM (United Nations Development Fund for Women), an organisation that is dedicated to raising awareness about violence against women and girls.
