Jessica Simpson's parents are reportedly fighting over financial rewards from their divorce.

Although Tina has already offered Joe $100 million of her $300 million fortune, her estranged husband - who manages both Jessica and his other daughter Ashlee Simpson - still wants more, including a bigger share of the profits gained from Jessica's clothing line The Jessica Simpson Collection.

A source told RadarOnline.com: "Joe's desperate to get his hands on the pot of gold and is pushing his lawyers to move the case to Los Angeles. Texas is both a fault and a no-fault divorce state, so he's concerned that Tina may be favoured by a judge there, after all she was the one that filed and is seemingly the wronged party.

"So, by moving the divorce to California, which is a no-fault divorce state only, Joe thinks he will likely get more sympathetic treatment and hopefully a larger chunk of Tina's wealth.

"Joe wants a more even distribution of the wealth. Tina has already offered him a settlement of around $100 million, but Joe is holding out for even more."

Following their break-up Joe has denied a number of gay sex allegations, but Tina stated their marriage ended when it became "insupportable because of discord or conflict of personalities."
