“We have a time frame, but that’s private!” Dunst adorably said when asked if she and Plemons, 28, have set a wedding date.
The actress was glowing on the red carpet in a black strapless Christian Dior gown that made her oval-shaped engagement ring stand out even more and rocked her favorite pair of matching Christian Lacroix ankle-strap pumps with flower embellishments.
Dunst and Plemons met on the set of season two of Fargo in 2015, where they played high school sweethearts Peggy and Ed Blumquist.
“I’m happy,” Dunst said of her beau, adding that you just know when you’ve met The One. “You just do. You do!”
Though Hidden Figures failed to take home any Oscars, Dunst was grateful to be a part of the film, which was nominated for three statuettes, including Best Picture and Best Supporting Actress for Octavia Spencer.
“I’m just so proud of the film and my fellow cast members, and the director [Theodore Melfi],” she said. “It’s a really fun group of people and I just loved working with Octavia. We live around the corner from each other, too! It’s nice to celebrate with good people who are also talented.”
