A dispute about a personal trainer has jeopardized an exercise video actress/singer and "Newlyweds" star Jessica Simpson was to make for fitness company SpeedFIT.

Simpson wanted trainer Michael Alexander, the person who got her into shape to play Daisy Duke for her film debut in "The Dukes of Hazard," to help her get ready for the exercise video, InTouch reported. However, SpeedFIT nixed Alexander, saying his workout style did not fit their image.

Video producers were mulling whether to bring a lawsuit in the multimillion-dollar contract Simpson signed.

Simpson's business manager said Alexander's help would increase the marketability of the exercise video and efforts were being made to resolve the dispute.
