Scarlett Johansson: My Fiancé Romain Dauriac Is My Buddy

"I'm very happy," Johansson, 29, says about Dauriac, 31, a journalist who manages a creative agency, in the new issue of PEOPLE. "He's my buddy."
The couple, who got engaged last August, do not want to "rush through it" and plan to take their time in planning a wedding. "Being engaged is an exciting time to enjoy and to really savor," she says.
In the meantime, Johansson, who is the new Global Brand Ambassador for SodaStream, stars in a Super Bowl commercial for the bubbly beverage maker on Feb. 2.
"I have been pushing SodaStream to my family for years. I buy it for my friends as housewarming gifts and I have it everywhere I go," she says. "When I film I have it in my trailer and they outfit the whole craft service table with it. I have it everywhere just because I love it so much."
Johansson, an avid cook, even makes tasty meals at home to go along with her carbonated drinks.
"I cook, but I'm no pro," she admits. "I was making a white chicken chili 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 chili!' 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!"
