The "Bring It On" star gave birth over the weekend, PEOPLE reports. “Everyone is doing great," a source told the mag.
This is the first child for Dunst and her fiancé Plemons after they met in 2016 on the set of the show "Fargo," where they played a married couple. They have since remained very private about their relationship and news of their engagement only became public when Dunst wore an engagement ring to the Golden Globes in 2017.
The couple's reps have yet to comment on the birth.
