Scarlett Johansson told Access Hollywood: "I don't plan anything. I'm terrible at planning. Yeah, I'm not gonna plan anything - I like to wing it!"
Meanwhile, she recently moved to Paris, France, with Romain, and admits she still needs to work on her culinary skills.
She said previously: "I cook, but I'm no pro. I was making a white chicken chilli and I had to let it reduce for a little while, so I was like, 'Let's go build a snowman while we wait.' I got a little carried away ... Three hours later, I was like, 'Oh no, the chilli!' I went back inside and the house was covered in smoke. A pro would have not made that mistake. Make sure to check every five minutes if you are reducing something!"
She said: "My signature baked good is a vegan banana chocolate chip muffin ... I can modestly say I have had marriage proposals from those!"
