And as well as wearing a dress to die for, the American Hustle actress totally nailed one of our favourite hair trends of the moment – the faux bob!
Amy joined the likes of fellow co-star Jennifer Lawrence, Kelly Osbourne and Isla Fisher at this year's glamorous event, held at The Shrine Auditorium in Los Angeles.
Dressed in a figure-hugging, royal blue Antonio Berardi gown, Amy took our award for hottest lady of the evening – an honour we're sure she'll prize just as much as winning Outstanding Ensemble in a Motion Picture for her latest film, American Hustle!
But as well as the amazing dress, sky-high heels and impeccable make-up (nice orange lippy, btw), we just love, love, LOVE Amy's stunning updo.
Amy chose a beautiful, 'old Hollywood' hairstyle for the evening which was rolled into a faux bob shape and perfectly showed off the gorgeous neckline of her dress.
The faux bob has been storming the red carpets recently, with Taylor Swift fast making it one of her go-to, signature styles.
And now that Amy's totally nailed the look and given it a super-glam 1920s feel, we reckon it's definitely a trend that's set to stay.
Amy's do is not the easiest look to achieve yourself but if you have patience and time, try rolling the lengths of your hair up into large heated rollers and pinning into place while they set.
When cool, carefully remove the rollers while still holding your hair into a roll, then pin and spray like crazy to keep it in place!
Or if in doubt, take this pic to your hairdressers and get them to do it for you – much simpler!
For a simpler (but no less gorgeous) take on the look, you could also take inspiration from Game of Thrones star, Emilia Clarke who worked another fabulous faux-bob at the SAGs.
Emilia's was a softer, more tousled do thats beauty was in its simplicity.
To copy her look, part your hair to one side then scoop it all over one shoulder, on the opposite side to your parting.
Next, grab the lengths of your hair, twist them loosely and pin the ends underneath to create a soft rolled look at the bottom.
