The toddler reportedly drowned in a pool at Dbanj's home in Ikoyi, Lagos.
Though the singer hasn't offered a statement, he did confirm the news with a blacked-out Instagram post captioned: "Trying Times. But my God is Always and Forever Faithful."
D'banj wasn't in the country during the accident as he was attending the BET Awards in Los Angeles.
At the same ceremony, Nigerian singer Davido payed homage to D'banj when taking home the BET International Act award. "I want to send condolences to my big brother, the actual artiste that paved the way for us to be on this stage, Dbanj my condolences I wish you. You're my brother," he said on stage.
D'banj is reportedly flying back to Nigeria with his wife.
Several other artists and celebrities have been offering their condolences online. See some below.
