Usher's eldest son is in intensive care in hospital.
The More singer's five-year-old son, Usher Raymond V, was rushed to a medical centre in Atlanta, Georgia, on Monday, after he allegedly almost drowned in a swimming pool at his home when his arm got stuck in a drain.
A source told gossip website TMZ.com that the little boy was playing in the water with his aunt when he dove down to retrieve a toy that was lying in the drain.
The insider said that his arm got stuck and his aunt immediately tried to rescue him but couldn't get his hand out.
A maid also dove into the water and started screaming for help when she couldn't release him.
