The "Good Luck Chuck" star who is expecting her first child with her movie producer fiancé Cash Warren - plans to tie the knot in a simple registry office service and then have a party with her friends.
Jessica, 26 said: "Everyone I know hates weddings. I've been to very big, beautiful and romantic weddings, but I would rather just throw a big party.
"I am probably going to go to get my certificate at the City Council, throw a big party for the family and that's about it."
The Hollywood sex symbol has also admitted she isn't looking forward to the sleepless nights when her baby is born.
She said: "My brother, who is one-and-a-half years younger than me, had a baby two years ago. All of my cousins, who are all younger than me, have kids, and I've done lots of baby-sitting.
"But it's nice to be able to hand them back at the end of the day - especially when they're not sleeping and they have a dirty nappy. Then you can get some rest!"
