Jessica Simpson is not a diva .

Vivica Fox tells PEOPLE she was “shocked� when a story surfaced of Simpson being a “spoiled brat� on set .

“Those vicious lies they put out were just that – lies,� Fox says. “She was so much of a team player. She was gracious and so down to earth. She showed a lot of physicality, like 90 percent of all her own stunts, and she sacrificed so much of her body for this movie.�

Fox also talked about Jessica's broken nose,

“During the scene,� remembers Fox, “she looked really intense when I looked in her eyes, and I just thought she was really into it. But when the director [Steve Miner] yelled, ‘Cut,’ Jessica came over to me and said, ‘Vivica I hit my nose with the gun.’ We got ice immediately … Most girls would’ve stopped right then and there, but she was ready to do another take. She’s wonderful.�
