The actress welcomed her second son, James Robert, over the summer (21), and admits she and Plemons were planning to wait to expand their family - and then the coronavirus kicked in while she was in Australia filming new movie "The Power of The Dog".
"We would go to the grocery store and take off our clothes and wipe down (everything) afterwards," she tells The Times about her COVID panic.
"No one knew anything, it was terrifying, and at the time I smoked so I was like, 'Oh my God, if I get this I am gonna die!' "
"I was like, 'As soon as we are done with this movie, let's try and have another baby.' "
Jesse and Kirsten are also parents to three-year-old son, Ennis.
The couple started dating in 2016 after meeting on the set of "Fargo". They got engaged in 2017.
The actress recently said she was too busy to plan a wedding. "I would marry him tomorrow. We want a proper wedding, we just haven't had the time. And I wanted to have fun at my wedding and not pay for everyone else to celebrate while I am pregnant and waddling down the aisle," she opened up.
She went on to suggest it wasn't love at first sight with her fiance. "I didn't think love right away. Although one of my best friends told me that I'd said to her, after about two weeks of knowing him, 'I will know him for the rest of my life.' There was an immediate soul connection," she explained.
