Braving the cold in a sleeveless frock, Emily joined the rest of her co-stars at a Mayfair screening of the latest Disney film.
Glamming up for the occasion, the 31-year-old opted for a beautiful white dress embellished with silver and gold studs.
The star teamed her outfit choice with a pair of nude barely-there sandals, sporting her ombre locks in loose curls. For her make-up, Emily made sure to dazzle with metallic eyeshadow and plenty of gloss on her lips.
At the event, mum-of-one Emily went solo on the red carpet, arriving without her husband and fellow actor John Kransinski. The couple share a daughter Hazel who was born last year.
Although, Emily was joined by her onscreen other half James Corden. In their latest movie which puts a modern twist on classic fairytales, the pair play 'the Baker' and 'the Baker's wife'.
Into The Woods boasts a star-studded cast including Anna Kendrick, Chris Pine, Johnny Depp and Meryl Streep - who Emily has previously worked with before on The Devil Wears Prada.
Earlier this week, Emily claimed she was "still in awe" of Hollywood great Meryl despite the pair now being close friends.
Speaking on This Morning, she said: "I still get so much inspiration from her. I've known her now for almost ten years and she's become such a friend to me and has been so wonderful to me in this business."
In the film, Meryl plays the role of a witch who has cursed James and Emily's characters to be childless.
Into The Woods hits cinemas on Friday 9 January.
