The 'Voice' coach has been locked in a bitter dispute with her former fiance over the care of their nine-year-old son David Jr. and now they will face one another in court for a five-day trial starting on the March 11 in order to resolve the questions of who should have a greater share of custody of the youngster and who should pay support.

According to The Blast, things are so bitter between the former couple, they have even been fighting over the choice of school bus stops.

Last year, Jennifer filed for an emergency order of protection after accusing the WWE commentator of pushing her while holding David, and though it was granted by the court, the 37-year-old singer later dropped the petition altogether.

Both David - who denied pushing his former partner - and the 'Dreamgirls' star have filed a number of motions against each other, accusing one another of playing legal games.

At one point, Jennifer said she was worried David would kidnap their son, while he accused her of trying to defame him.

He argued she had made creative negative press about him her priority, rather than protecting their only child.

In court documents, David claimed Jennifer issued an exclusive statement to People about their split, saying her actions were "solely taken in the best interest of their son", at the same time he was being served with an emergency order of protection.

He alleged the statement damaged his reputation and at the time it was released, he was being forcibly removed from their home in front of their son, and Jennifer wasn't even there.

A court order is in place prohibiting the former couple from disseminating photos or making comments about their son, but the wrestling star previously claimed the 'Spotlight' singer had violated the order by giving an interview to an entertainment news show, which showed various photos of David Jr., and mentioned him by name throughout.
