Kate Hudson & Matt Bellamy fighting over money

Kate Hudson is at war with her baby daddy Matt Bellamy!

Sources say the Bride Wars actress and the Muse rocker who are engaged and expecting their first child together are fighting over money.

“Kate and Matt are clashing over money issues… and it may destroy any chance they have of getting married. Their relationship was in a much healthier place before he put a ring on her finger,” an insider told Star magazine.

Kate is insisting on a pre-nup because she has more money than Matthew, and the proposed agreement is tougher on him than her.

“He would be on a payment plan of sorts, where he is allotted a certain amount of money annually… and if he cheats, he will lose everything, but if she cheats, no harm, no foul. The fighting over the pre-nup has soured the experience… they may not get married at all. They may just stay engaged, or even split up.”
