from www.radaronline.com – A new Jesse James mistress has been found by RadarOnline.com and unlike the women that have spoken publicly of their flings with Sandra Bullock’s husband, this woman was in a serious relationship with the West Coast Chopper owner.

Two strippers and a fetish model have revealed their affairs with Jesse while another woman hired attorney Gloria Allred but never came forward. Now RadarOnline.com has discovered a FIFTH woman and Jesse was in love with her.

“She had a full-on relationship with Jesse,” a good friend tells RadarOnline.com of the mistress who wishes to remain unidentified. “After a while Jesse became obsessed with her and she couldn’t handle it anymore.

“If he couldn’t get a hold of her for some reason he’d go over to her house looking for her,” the source said. After a while, “she got kind of scared of him and broke it off.”

As RadarOnline.com reported previously, Jesse spent several hundred thousands of dollars on his mistresses over the years, using chartered jets to fly them around and spending several days a week in strip clubs.Now a source close to the new mistress tells us there was another expense.

“Jesse got a house for this woman and she said he paid the rent on it every month,” the source told RadarOnline.com. “She said he only stopped paying for it once she broke up with him.”

While Jesse never flaunted his cheating, residents of his Long Beach, California neighborhood tell RadarOnline.com that it was no secret he was stepping out on Sandra. “Everybody knew what a dog he was. We always felt bad for Sandra, but it’s not our business,” the source said. “Jesse was put on a pedestal in this town so no one ever questioned him.”

Jesse is currently in sex rehab at Sierra Tucson in Arizona and hoping to save his marriage. As previously reported by RadarOnline.com, Sandra is hiding out at her Hollywood Hills home while she figures out the best approach to filing divorce papers on Jesse.
