The We're The Millers actress - who is the niece of Hollywood royalty Julia Roberts - rocked a beautiful, ladylike 'do while attending the Z100 Jingle Ball in Madison Square Garden.
Emma nailed things with her outfit for the evening, teaming a checked strapless top with tailored black trousers while injecting a pop of colour with pillar-box red patent courts.
Her make-up was totally flawless too, with the starlet adding drama to her peepers with thick kohl pencil complemented by a pop of orange-red lipstick on her pout, plus a metallic silver manicure.
But our fave part of her look had to be her golden locks, which had been effortlessly swept over her shoulder with the lengths styled in bouncy, princess-like waves.
With the festive party season just around the corner we've been looking for a new glossy hairstyle to try out, and this one is just the ticket!
Here's how to get the look...
1. Starting with freshly-washed hair, spritz your strands with a heat defence spray. We're fans of L'Oréal Paris Elnett Volume Heat Protect Spray, £7.49 - not only does it protect your bonce up to 230°, it also helps to detangle. And when it comes to brushing wet hair, we swear by The Wet Brush, £8.99, which has special flexible bristles to ease knots.
2. Next, apply a hair oil through the mid-lengths and ends of your locks to add gloss and help smooth the texture of your hair. We're fans of Bumble and bumble Hairdresser's Invisible Oil, £31, which leaves hair feeling soft and silky without weighing it down.
3. Once your hair is dry, part it on one side before bringing the lengths over one shoulder. Next, section your hair into smaller parts, before using a heated wand to create loose waves. The GHD Curve Classic Wave Wand, £110, boasts an oval-shaped barrel which is perfect for creating classic, defined Hollywood waves like Emma's, plus it includes a ceramic coating which makes hair appear smoother and shinier.
Take a section of hair that's about the same width as the barrel of your wand, then, holding the wand vertically, wrap your hair around it before holding for 5-10 seconds. Make sure you only curl the mid-lengths and ends of your locks, as we want to keep the roots smooth.
4. Once you've finished your waves, take the very front section of your hair and pull it to one side before securing with a bobby pin. You might want to add a bobby pin at the back of your head near the nape of your neck too, which will help encourage your locks to stay swept over one shoulder.
5. Finally, gently ruffle your lengths with your fingers to help separate the waves, before fixing your look in place with a spritz of hairspray (we love Aussie Miracle Hairspray Shine + Hold, £3.99 - it smells amazing!).
