She is currently going through a no doubt difficult divorce with her husband Seal.

But it is certainly not affecting Heidi Klum's appearance. In fact, the German stunner is looking better than ever.

The 37-year-old was at her supermodel best in a shimmering low-cut and backless dress for the DKMS Linked Against Blood Cancer gala at Cipriani Wall Street in New York City this evening.

The blonde beauty showed off plenty of skin in the gown, which featured a plunging neckline.

Heidi let her dress do all of the talking by accessorising with two pieces of jewelry, including some diamond chandelier earrings and a large cocktail ring.

Actress Dakota Fanning also attended the event and opted for another hue of metallic.

The 18-year-old was ethereal in a soft gold gown featuring an embellished bib.

The delicate hue complemented her blonde locks, which she wore down in a soft natural style.

She carried a gold clutch and slipped two Cartier 'Love' bracelets on her arms.

Meanwhile Melissa George's outfit almost blended into her skin tone as she graced the red-carpet.

The 35-year-old former Home & Away star wore a fitted nude dress, which gave the illusion of two-piece outfit with it's consisting corset-style top and a more flowing skirt.

She accessorised with a cream clutch and matching pair of towering platform shoes.

Earlier today Heidi was seen atop the Empire State Building attending a lighting ceremony to honour bone marrow donors.

The cause is certainly a worthy one.

DKMS is the largest bone marrow donor centre in the world, and works to help people donate life-saving bone marrow.

Heidi has certainly had a busy day, fitting several other commitments around her charity appearance.

After her trip up the Empire State Building the star rushed off to attend to some business matters.
