The 'Total Recall' star revealed that so far her only plans are to include a bakery inside her eatery.
31 July 2012 She told 'The Tonight Show with Jay Leno': "I would have the bakery component. I say I'm into it, but I'm not a great baker - yet.
"Baking is really very mathematical and I'm terrible at math. I'm a really good loaf person. I do loaves - but sweet loaves - like zucchini loaf or banana loaf or banana blueberry loaf. It's really good!"
The actress went on to ask viewers to encourage her business venture.
She said: "Please come to my restaurant. It's going to be called Oh Fudge."
Jessica is engaged to singer and actor Justin Timberlake, who has a restaurant in New York City's Upper East Side called Southern Hospitality.
Despite following in the footsteps of her partner, the actress recently admitted that she often conforms to the other person's lifestyle when she finds love.
She said: "In my earlier experiences with relationships, I really was vulnerable to somebody else's personality, hobbies, and way of life.
"But as I've gotten older, I've become proud of the traits that make me who I am. Maintaining my individuality is really important to me because otherwise I can easily slip into somebody else's life. So I'm glad I'm getting better at it. It's a process, but it's getting simpler."
