Sienna Miller oozes androgynous chic in a tux as she joins glam Kate Winslet, Benedict Cumberbatch and James Norton at A-list carol service hosted at St George’s Church

Sienna Miller, Kate Winslet, Benedict Cumberbatch and James Norton were among the Hollywood elite who attended a star-studded carol service on Wednesday night.

The group of celebrities were seen leaving St George’s Church after the Christmas Story Appeal last night in Hanover Square, London.

Sienna, 42, cut a great figure in a black tuxedo and bow tie ensemble, which she paired with a white shirt and a pair of statement earrings.

The actress wore her dark blonde locks in a sleek updo and opted for a glamorous coat of makeup with a dusting of red lipstick.

She accessorized it with a red clutch and added height to her petite figure with a pair of simple stiletto heels.

The stars enjoyed performances by the Scots Guards Trumpeter Band and Fanfare and the Westminster Cathedral Choir.

Famous readers include Rowan Atkinson, Simon Callow, Victoria Coren Mitchell, Benedict Cumberbatch, Rupert Everett and Aled Jones.

The congregation also heard from Ian Hislop, Lord Bishop of London, Sienna Miller, James Norton, David Mitchell, Hussina Raja, Sophie Raworth, Julia Sawalha, Adrian Scarborough, Dan Snow and Kate Winslet.

This year’s charity event raised more than £1 million for the first time in the event’s 47-year history.

Elsewhere at the event, Kate, 49, looked incredible in a white satin jacket which she paired with silky black trousers and black stilettos.

She wore her locks in soft waves and opted for minimal makeup, while accessorizing with a selection of gold necklaces.

Meanwhile, Benedict, 48, opted for an elegant blue velvet jacket, which he paired with suit pants, a white shirt and a black tie.

James Norton looked equally dapper in a sharp suit and red patterned tie, while adding a pair of aviator-style glasses.

After his reading, Rowan left the church in his classic black tuxedo, while carrying a copy of the event program.
