Sandra Bullock and Jesse James have a prenuptial agreement that specifies he gets no money in a divorce if he cheats during the marriage it is being reported.

While James is financially successful on his own, Bullock is Hollywood’s top actress after her Oscar victory and commands top paychecks.

“If she divorces Jesse and proves he was cheating, which won’t be hard, Sandra won’t have to pay Jesse anything,” a source familiar with the situation said.

James had been undergoing sex rehab at Sierra Tucson in Arizona, James has bolted from the facility after Bullock refused to take a call from him. James’ friend and lawyer describe him as a “broken man.”

Bullock told James she is going to divorce him but has not yet filed papers. She has stayed out of public since James’ cheating was exposed and has spent most of the time in her Hollywood Hills home.
