(Cover) - EN Showbiz - Usher is facing a court battle today over the custody of his two young sons.

The singer and his ex-wife Tameka Raymond are in court in Atlanta, Georgia to try and settle their dispute.

TMZ reports that they have received an ultimatum from the judge to try to come to an agreement or have the court decide for them.

They are now in private mediation to agree on temporary custody terms otherwise they will face the judge again later today.

The order will decide on how Usher and Tameka split their time with their children and also how much child support she will receive.
