Surprise! Kirsten Dunst and Jesse Plemons are engaged, Us Weekly confirms. The Fargo costars, who played married high school sweethearts during the second season of the show, first sparked romance rumours when they were spotted kissing in LA back in May, just one month after Kirsten ended her four-year relationship with Garrett Hedlund. This will mark the first marriage for both. Congrats to the happy couple!
