The actress, who stars as Mia in box office hit La La Land, stole the spotlight as she opted for a stunning lingerie-inspired gown for the star-studded event.

She ditched her bra as she sported a revealing dress, which featured a sheer black lace corset and left very little to the imagination.

The star’s sizzling Alexander McQueen number featured a velvet skirt which was embroidered with floral detailing and was draped across her chest.

Emma’s trim waist was highlighted by the chic ruffle detailing across the gown, while the corset-style top showcased her enviable physique.

She flaunted her décolletage in the low-cut garment, which featured very thin spaghetti straps to hold everything in place.

To complete her head-turning attire, she wore black heeled sandals and carried a satin clutch bag, while she dazzled with diamond drop earrings.

Emma wore her red locks in a chic wavy 1920s style while she sported smokey eye make-up to compliment her gown.

Speaking on the red carpet about her character in La La Land, she told E!: “I relate to pretty much every audition in the movie.

“I’ve had a version of those many, many times. I think the hardest part was, for a while, I auditioned for a lot of things, which is great when you’re an actor and you’re getting a lot of auditions.

“But, I wasn’t getting called back for anything when I first moved to LA and so, they just stopped sending me out.”

Also at the Screen Actors Guild Awards last night, was The Crown star Claire Foy who was reunited with her onscreen husband Matt Smith.

The pair cosied up on the red carpet with the actress looking phenomenal in an sweeping embroidered Valentino number.

She oozed glamour as she joined her co-star who looked very dapper in a black tuxedo and suede shoes.
