Emma Roberts Flaunts Her Engagement Ring At 2014 Golden Globes (VIDEO, PHOTOS)

Emma Roberts has that bride-to-be glow!

The "American Horror Story Coven" actress, who got engaged to co-star Evan Peters over the holidays, showed off her gorgeous engagement ring at the 2014 Golden Globes on Sunday.

Although the 22-year-old and her fiancé didn't discuss the details of the ring, an expert told E! News that it looked like a yellow or rose gold round-cut diamond, about 2 to 3 carats and probably cost an estimated $37,000-$50,000.

The news of the couple's engagement came as a bit of surprise as the twosome have undergone a lot of downs in their relationship, which began in 2012.

Last July, Emma, the niece of Julia Roberts, was arrested for reportedly attacking Peters in a Montreal hotel and was later photographed crying into Evan's arms after the news of her arrest broke.

Regardless, the couple seemed to have moved forward and they looked happy and healthy at the Golden Globes, where Emma rocked a black Lanvin gown and turquoise chandelier earrings.

But what we really want to know is: What does aunt Julia think of her niece's engagement?
