Kelis has welcomed a baby boy. Knight Jones -- who weighed 7.8 lbs. -- was born Wednesday around 9 p.m. in New York City, a rep for the 29-year-old singer tells Usmagazine.com.
Adds the rep, "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.
It is the first child for the "Milkshake" singer. The baby's father is rapper Nas, with whom she split while seven months pregnant.
Both sides are also seeking joint custody of the child.
