Dressed in a fishtail black Lanvin gown, Emma turned heads as she struck a pose on the red carpet. The 22-year-old teamed the outfit with a matching black Kotur clutch and dangling turquoise earrings, but all eyes were on her pink gold and diamond ring.
The petite actress had no need to think about dieting before the awards ceremony at Beverly Hills, and shared a photo of herself tucking into an In-N-Out burger earlier that day.
"Snack before the globes," tweeted Emma to her 2.5million followers.

Emma and Evan, who have been together since 2012 after meeting on the set of dark comedy film Adult World, weren't the only loved-up couple at the Golden Globes affair.
Newly engaged Robin Wright and Ben Foster looked in high spirits as they posed together on the red carpet. The beaming House of Cards actress, 47, dazzled in a glittering Reem Acra halter gown that matched her gold engagement ring.

Robin flashed a smile at the cameras and clearly had much reason to celebrate as she scooped the award for Best Actress in a TV Drama.
Accepting the trophy, Robin made no specific mention to her actor fiancé but later spoke about the couple's wedding to People.
"It's still new," said Robin, who will be walking down the aisle for a third time. "We're still talking about where, when, how, but couldn't be happier."
