Meanwhile, the 'Dukes of Hazzard' star has confessed she dresses sexily to impress men.
Jessica admits she chooses outfits she knows will send men's pulses racing, and is happy to make the most of her desirable body.
She said: "I dress for men, and also for myself. But if I am dressing for men, then I know it's good for myself.
"Curves are better. Honestly, movie stars should be voluptuous and beautiful, and models should be voluptuous and beautiful."
