The 29-year-old 'Her' star recently fulled speculations that she is expecting her first child with Dauriac, reported People magazine.
"It's lovely to be engaged. It's a nice romantic time. My French is terrible," Johansson said.
The actress has a lot of places on her mind to settle down with her fiance.
"I've been thinking lately that maybe it's good to move to some faraway country where you can ski. I was thinking, maybe it would be nice to move to Switzerland," she said.
The couple first went public with their romance in November 2012.
