Concealing her enviable figure, the Burnt star layered a maroon cricket style jumper over a white shirt. 

She teamed the garment with cropped black trousers that flared out to expose a pair of open toe mules.

All eyes on her: Beaming broadly as she posed for snaps, the 34-year-old actress oozed glamour at the event - where she was promoting her new film, Live By Night

Sienna was at the headquarters to discuss her new film, Live By Night, where she stars alongside Zoe Saldana and Elle Fanning.

She plays Emma Gould, the mistress of a powerful mobster in the movie - which is set for release on Christmas Day - a year later than expected.

Set in the roaring 1920s, the movie is centered around a group of individuals and their dealings in the world of organized crime during the Prohibition Era.

As well as directing the film, Ben Affleck also stars, playing a gangster.

In a teaser trailer released on last month, he is seen playing Joe Coughlin, the son of the Boston police superintendent, who chooses to live the life of an outlaw, turning his back on his strict upbringing.

Chris Cooper, Brendan Gleeson and Chris Messina also star in movie based on the book by Dennis Lehane.
