Kelis welcomed a son on Tuesday around 9 p.m. in New York City, a rep for the 29-year-old singer told Us magazine.
Knight Jones, the singer’s first child, weighed 7.8 lbs. The rep added, “The beautiful baby boy and his mother are doing wonderful.”
Kelis had been in labor since 2 a.m. Monday and had a natural birth, with her mother and sister by her side in the room.
The baby’s father is rapper Nas, with whom she split while seven months pregnant. The two are currently embroiled in a bitter divorce, as Nas has asked a court to deny Kelis any spousal support that she has requested.
Both sides are also seeking joint custody of the child.
