( CNN ) -- Singer Usher Raymond 's ex-wife is asking a judge to give her custody of their two children after the oldest suffered a `` near-death accident . '' Five-year-old Usher Raymond V nearly drowned `` in a swimming pool and is currently hospitalized in the intensive care unit of the Children 's Healthcare of Atlanta Hospital , '' Tameka Foster said in an emergency motion filed Tuesday in a Fulton County , Georgia , court . Her son `` is doing much better , '' according to a Twitter posting by Foster on Wednesday afternoon . The mother has been with him at the hospital since she learned of the accident Monday , her lawyer told CNN . A hearing is set for an Atlanta courtroom Friday afternoon for the motion , her lawyer said . The other child , Naviyd , is 4 years old . In a statement released Wednesday , Usher said : `` I am blessed and fortunate to say that my son Usher V is doing well and is recovering . I am overwhelmed by the outpouring of prayers , love and support for my family 's well-being . '' The singer did not address his ex-wife 's allegations or the upcoming hearing . Usher won primary custody of the children last year after a bitter court fight in which Foster accused the singer of being an absentee father . Foster renewed her arguments based on Monday 's accident , contending the singer `` continues to excessively travel , utilizes third-party caregivers to supervise the minor children rather than personally exercising parenting time and providing supervision for the minor children . '' Usher is `` not capable of providing daily caregiving and supervision for the minor children of the parties as petitioner is preparing to film a movie in Panama and has ongoing commitments that require his presence in Los Angeles , New York and various other cities for the Voice and his upcoming album . '' Her motion alleges that Usher is away from Atlanta -- where she and the children live -- `` in excess of 85 % of each month . '' He refuses to let her see the children when he leaves town , saying he `` would rather the nanny raise the children , '' Foster contends . Foster also complained that her ex-husband does not talk to her about issues affecting the boys , `` including school enrollment and summer activities . '' The private school in which he just enrolled them is more than an hour from her home , she said . And , Usher has not given her the phone number to the home he moved to with the children in June , she said . Foster 's tweets posted Wednesday read : `` Cabin fever.. But I 'm so happy to say that my son is doing much better . Talking & asking for food . Thank you for ur well wishes & prayers . '' and `` ... .And no I have n't gone anywhere or done anything . # Relax '' Foster blames the swimming accident on `` the negligence and failure to properly supervise '' the children . Usher 's aunt was in charge of the children when the oldest son `` suffered a near-death accident while left unsupervised in a swimming pool , '' the motion contends . `` I need an ambulance , '' his aunt , Rena Oden , told an emergency operator in a call to 911 . `` My nephew was in the pool , and I could n't get him , I tried to get him . '' A recording of the call was made public by police Tuesday . The aunt , a housekeeper and another woman were `` unsuccessful in pulling the victim from the pool drain , '' but two men who were installing sound equipment in the home rushed to help , the report said . `` They 're doing CPR on him now , '' Oden told the operator . `` Is he coming around ? He 's breathing ! '' Sound technician Eugene Stachurski rescued the child from the drain and used CPR to revive him on the side of the pool , the police report said . About five minutes into the recording , Oden told the operator that paramedics had arrived at the home and had taken over . The child was `` conscious , alert and breathing '' when the ambulance took him to a hospital , where he was kept overnight for observation , the police report said . Usher 's former stepson -- also Foster 's son -- died in a watercraft accident on a north Georgia lake last year . CNN 's Tory Dunnan and Marylynn Ryan contributed to this report .
