Make-up free Sienna Miller embraces the natural look as she steps out in khaki jacket and casual tracksuit bottoms in New York 

She's been keeping a low profile of late following a busy year for her acting career.

And Sienna Miller was embracing a casual look when she stepped out in New York City on Wednesday, forgoing make-up and letting her natural beauty shine through.

The 34-year-old star was equally low-key when it came to her wardrobe, sporting a pair of loose-fitting tracksuit bottoms as she pounded the pavements.

Natural beauty: Sienna Miller was embracing a casual look when she stepped out in New York City, forgoing make-up for her morning walk on Wednesday 

Sienna wrapped up in a padded khaki jacket, knotting a neon trimmed scarf around her neck for extra warmth.

She embraced comfort in a pair of white trainers, slinging a bright yellow handbag under one arm.

The screen star blended in with the crowd as she sauntered along the busy street.

The British beauty, who has relocated to the US for her career, recently confessed she was considering leaving the US should Donald Trump become President.

Following the Republican candidate's surprise victory over Hillary Clinton, Sienna is no doubt rethinking her life plan.

'I don't know if I can stay if it goes the wrong way, so I'm really hoping that Hillary comes through,' she told Variety.

'It was really funny initially until I realised [Trump's candidacy] wasn't a joke... I'm really horrified.

'I've never been here for an election. I've never felt as invested in the outcome as I do now.'

Sienna's latest film is The Lost City of Z in which she plays the wife of real life British explorer Percy Fawcett (Charlie Hunnam) who made several attempts to find an ancient lost city in the Amazon.

He and his son eventually disappeared back in 1925 in search for the city.
