Janina James Coan, who was involved with Jesse's dad since Jesse was 6, tells TMZ she was "appalled" by what Jesse said about Larry James during the "Nightline" interview.
Coan -- who married Larry when Jesse was in high school but eventually divorced -- tells us Jesse had a variety of injuries -- including broken bones -- as a kid, because he was into motocross. But she scoffs at the notion that Jesse was abused.
Coan says, "Larry was the most caring father, the kindest father who would do anything for anybody. He loved Jesse to death and would brag about him all the time."
Coan does say, however, that Jesse and his dad don't get along. The tension started, she claims, when Jesse was 16. She claims Jesse's dad found out his son and a friend allegedly robbed a Fotomat and called the cops on him. Coan says Jesse ended up in juvenile hall and was very upset that his dad turned him in.
