Stunning in a racy black jumpsuit with a plunging neckline and cut-out design, the 45-year-old actress showed off plenty of skin during her appearance at the Princess of Wales theatre.

Flashing her signature smile for the cameras, Naomi confidently posed in the sultry number which revealed a generous glimpse of her cleavage. 

The sleeveless outfit showcased her slender arms and she went on to accentuate her plunging neckline with a glimmering silver pendant necklace sitting low on her chest.

With its cut-out designs revealing Naomi's taut waist, the jumpsuit finished at her ankles. 

Sporting a pair of metallic silver heels, the actress added some further sass to her red carpet strut.

She accessorised with a pair of sparkly earrings and a sleek metallic clutch and even clutched onto her own umbrella when the weather turned a little grim.

Mixing up her look, the movie star added a rock chic edge to her beauty regime, sporting a smoky eye shadow while her blonde tresses were pulled back in a voluminous ponytail. 

Naomi stars in the dramatic film St Vincent alongside the likes of Melissa McCarthy and Chris O'Dowd.  

Earlier in the day Naomi was spotted enjoying a stroll in Soho, New York. 

Sporting a relatively more casual look, the actress exuded confidence in a pair of blue jeans teamed with a white T-shirt.

No stranger to taking her casual chic look to the next level, Naomi added a popping pink coat to finish off her Big Apple style. 

Her long tresses were worn out, while she kept a low profile with a pair of dark sunglasses as she roamed around in her comfortable running shoes. 

The British-born Australian star stepped out without her hunky beau of 10 years, actor Liev Schreiber, with whom she has two sons, Sasha, eight, and Samuel, seven.
