The singer-and-actress - who is engaged to former NFL player Eric Johnson - has revealed that she has set a date for the big day and is exercising to make sure she looks her best when she walks down the aisle.

She said: "I have a date - I`m really excited!"

"I am going to dance around my bedroom and hopefully lose some weight - and lift some weights and do what I can!"

However, the 30-year-old blonde refuses to follow restrictive diets or spend hours in the gym, preferring to tone up in a way that`s less demanding.

She explained: "I just have to work out on my own. There is no regimen I need to follow. There`s no diet I need to follow. I just need to do some things for myself and that`s it. And that will make me feel the happiest."

Jessica is also thinking about what dress she will wear and can`t make up her mind which one to choose.

The beauty told Us Weekly magazine: "I`m still trying to figure out what to wear! I don`t know if I want the big boom, or the curvy thing, but it will be something beautiful."

Whatever she chooses is likely to be revealing, with the `Dukes of Hazzard` star recently saying she wants to show off her assets.

Using the French term for neckline, she said: "I have a long neck, so I like to show off my decolletage."
