It was a courtroom surprise yesterday. Pop star usher, taking the stand in an emergency hearing. Fighting his ex-wife for custody of their two sons when one of them nearly drowned in usher's pool. Abc's steve osunsami was in the courtroom. And steve joins us from atlanta live. Steve? Reporter: Good morning, bianna. The singer's 5-year-old son is still hospitalized here. When he goes home, he will go home with his father, to the very house where he nearly died. I don't know if my son is going to have a brain defect. I don't know if his heart is operating correctly. I don't know that my son is going to be 100% the boy he was. Reporter: At this emergency hearing, where tameka raymond hoped to win temporary custody of their two children with grammy award winner, usher raymond. He doesn't answer the phone. He doesn't answer e-mails. Reporter: Very frustrated. She broke down listening to the 911 calls from monday, when her 5-year-old son nearly drowned at the bottom of her ex-husband's pool. Her superstar former husband, who won custody of the kids last year, still wearing the wristband from his son's hospital. Acting as any father would, out of concern. Reporter: Telling the judge, he and the people at the house did the best they could. When they got into the ambulance, he was hysterical. I did my best to calm him down. I saw that he was gasping for breath. So, I know that he probably took in a fair amount of water. Reporter: Usher raymond v had his hand caught in the pool drain when reaching for a toy. He was under eight feet of water. And his father has video of the entire incident. Tameka raymond, questioned the ability of the aunt who was watching the children and testified friday. Rena oden jumped in the pool but couldn't free the boy. She's a good person and a nice family member. A nanny? No. Reporter: The judge disagreed, siding once again with the singer. Most of the people in this room have been considered for by a grandmother or an aunt. So, I'm denying, dismissing the motion. Reporter: Before he left court, he and his ex-wife embraced. Somehow these two have to work together. Mr. Raymond, in the future, you would be well-advised to keep your former spouse informed about your whereabouts and who is taking care of the kids. Reporter: In court, usher was asked a very important safety question, whether he ever looked inside and saw the bottom of that pool. He answered that he had people who took care of that. And he never noticed anything wrong. Dan and bianna? Steve, thanks to you. It was nice to see that embrace at the end. Share two kids. No question about it.
