Emma Roberts and boyfriend Evan Peters walked the Golden Globes 2014 red carpet together following news that the couple has become engaged.

According to E! News, the "American Horror Story: Coven" costars hit the awards ceremony hosted at the Beverly Hilton Hotel in Beverly Hills on Sunday, January 12th.

Watson looked gorgeous wearing a black Lanvin gown, which she accessorized with Neil Lane earrings, Jennifer Meyer and Chopard rings, Charlotte Olympia heels and a Kotur clutch.

However, we can't forget her stunning engagement ring which was given to the 22-year-old by Evans, 26. According to Glamour, the blonde beauty's rock looks like a 3-carat round diamond in a diamond halo on a pave band with a rose gold setting.

This marks the couple's first public joint public appearance together on a red carpet since getting engaged over the holidays.

Emma Roberts and Evan Peters attended the ceremony because their FX show was nominated in the Best Miniseries or Television Film category but lost to HBO's Behind the Candelabra.

"American Horror Story: Coven" star Jessica Lange was also nominated in the Best Actress in a Miniseries or Television Film category but lost to "Top of the Lake" actress Elisabeth Moss.

Following the big show Roberts and Peters headed over to the FOX/FX Golden Globe Party at the FOX Pavilion.

A source revealed that the newly engaged couple spent the night "dancing with friends, singing along to Rihanna's 'Please Don't Stop the Music' and chatting with Jessica Lange.

"[Costar] Taissa Farmiga joined and hung out and took photos. Emma and Evan were making their rounds around the party."

The happy couple has yet to make an official announcement confirming their engagement.
