Jesse James affairJesse James' mistress count keeps rising, but the fourth woman claiming to have had an affair with the West Coast Choppers founder won't be going public with her story.

The unnamed woman, who claims to have carried on a three-year affair with James while he was married to Sandra Bullock, recently hired powerhouse attorney Gloria Allred to represent her.

"I can confirm that she has decided not to tell her story," Allred explained Monday, Usmagazine.com reports. "I have no other comment."
