The business plan was thought up by Jessica's father and manager, Joe
Simpson, 48.
A source told America's Life and Style Weekly magazine: "Joe's going to make
a lot of money from this."
The flagship eatery will open in Las Vegas' Caesar's Palace next year, and
Jessica will reportedly commit to make at least five appearances at the
venue each year.
A spokesman for the 26-year-old star, whose divorce from Nick Lachey was
finalized this year, has so far refused to confirm the restaurant plans.
Jessica Simpson recently confessed to sleeping in Nick Lachey's T-shirts.

She says, "I still have some of them. I don't throw away things. I love Nick with all my heart. He's still a dear friend.

"He's part of who I am. He's a part of what happened to me. We grew up together. I fell in love with him when I was 19. That's young."

Earlier this week, Jessica and her sister Ashlee were slammed by a Christian
minister for using sex to sell their music.
Reverend Bob Harrington, also attacked father Joe - who was formerly a
Baptist minister.
Harrington fumed: "Their father has replaced his faith in the Lord with the
love of money, which is the root of all evil. He has replaced holiness with
horniness.
"Jessica and Ashlee will reap the dismal crops they are sowing. Their
breasts will sag and their faces will wither and they will be left with
nothing but a hollow shell."
