The spotlight may have been on her charitable efforts, but Natalie Portman stole the show for her fashion as she hit the red carpet in an elegant metallic gown on Saturday.

The Oscar-winning actress was one of the honourees at the Children's Hospital Los Angeles Gala: Noche de Ninos at LA Live.

The 33-year-old was stunning in a gorgeous Grecian-style draped silver gown as she was accompanied by husband Benjamin Millepied.

At the event, Natalie turned heads wearing a sleeveless metallic frock that ruched at her waist and draped at the neckline, perfectly complementing her petite frame.

The mom-of-one wore her long brunette locks around her shoulders and kept her makeup looking natural.

She simply accessorised her ensemble with a maroon satin clutch and made her dress the statement piece.

At this year's event, Natalie was awarded the Courage To Care Award for her dedication and support of the hospital's mission and the patients.

She first became involved in 2008 as a volunteer and since then has donated funds to support programs for families in need.

The black tie celebration was inspired by a young cancer patient whose last wish was to inspire others to have the courage to care for sick children.
