Usher Raymond said his 5-year-old son is getting better after a pool-related accident earlier this week that resulted in his ex-wife filing for custody of the child.

"I am blessed and fortunate to say that my son Usher V is doing well and is recovering," the 34-year-old singer said in a statement sent to ABC News by his spokeswoman. "I am overwhelmed by the outpouring of prayers, love and support for my family's well-being."

Usher Raymond V, the son of "The Voice" coach, was rushed to the hospital Monday following a poolside accident in which the child got his arm stuck in a drain while playing at the performer's Atlanta home.

The singer's aunt, Rena Oden, and a housekeeper tried to free the boy, but two men working at the home had to step in, free the child and then give him CPR.

"I would like to thank my Aunt Rena as well as the doctors and nurses who are working with us around the clock," Usher's statement said. "I would especially like to thank the two men who saved my son's life, Eugene Stachurski and Ben Crews. They are true heroes and I am deeply grateful to them."

After the accident, Usher's ex-wife, Tameka Raymond, 42, filed an emergency custody request late Tuesday in Fulton County, Ga., Superior Court. Emergency custody orders are used when it appears to the court that removal of the child is in his or her best interest.

The hearing is set for 2 p.m. on Friday.

Usher was not present at the time of his son's accident, which is part of Tameka Raymond's reasoning for the motion to have custody of the boy.

In the motion, Tameka Raymond accuses Usher of "negligence and failure to properly supervise the minor child." She also claims he uses "third-party caregivers" as much as 85 percent of each month, while he is out of town filming "The Voice" and for his new album.

Usher and Tameka Raymond were married in 2007, and Usher Raymond V was born later that year. The couple had another child, Naviyd Ely, the next year but divorced in 2009.
