Sandra Bullock helped raise Jesse James' 6-year-old daughter, Sunny, while the girl's mother, porn star Janine Lindemulder, was in jail for tax evasion. Now, despite having lost a custody battle just last December, she is renewing the fight. TMZ is reporting that Lindemulder has filed legal documents as a direct result of James' affair with tattoo model Michelle "Bombshell" McGee.

But even if James slept with a Nazi fetishist, does it give a longtime porn star a decent shot at custody? For an expert opinion, PopEater chatted with J. Michael Kelly, who specializes in paternity cases in Los Angeles.

"One thing that a judge takes incredibly seriously when children are involved is pornography," Kelly says. "The judge will look at the larger moral character of both parents, but I do not think Janine Lindemulder has a chance at gaining full custody of Sunny James."
