As news comes of Jesse James' citation for vandalizing a photographer's car and his wish to remain married to Sandra Bullock, a source tells that Jesse cheated on Sandra just weeks into their marriage in 2005.

"Jesse admitted to Sandra that he has been cheating since weeks after they were married," the source said.

While he was having all this unprotected sex, Jesse also got a mistress pregnant, reports. The source said that Jesse knew about the pregnancy, and the mistress did not have the baby.

As for Jesse's three kids, they are at home in Seal Beach, California, "with a woman who looks like a grandmother-type," a source tells Us Weekly.

"If she is aware of the crisis going on at home, you wouldn't know it by looking at her," the source said of Jesse's six-year-old daughter, Sunny.
