The couple, who was married from 2007 to 2009, has been embroiled in custody dispute over their two sons Usher Raymond V, who goes by Cinco and Naviyd Raymond, ever since their split, reported Daily Express.
Usher, 34, is said to have stormed out of a co-parenting class the couple were ordered to take together in July. Foster is reportedly urging the judges to order the singer to be a better parent as she thinks he is uncooperative when it comes to making important family decisions.
