Johansson has been dating Dauriac, a French journalist, since November 2012. They've been engaged since September 2013.
In a recent interview with Parade magazine, Johansson said she was in no rush to tie the knot.
"I don't feel like I need to rush that part of my life. I can let that happen organically," she said. "Right now, it feels like a time to enjoy and be relaxed and that's what works for us."
She did, however, dish to Harper's Bazaar last October that she eventually wants to have kids.
"Eventually I want to have a family, and that would be my focus, but right now I'm having fun with it. There have been times in my career where I've struggled to find ... I was stuck for a while. It was more difficult, maybe, to find the right thing to do. Now I'm enjoying a really productive, creative period," she said.
