Kelis welcomes first child

Father is soon-to-be ex-husband Nas

NEW YORK -- Kelis has welcomed her first child, a boy named Knight.

Her representative, Tracey Nguyen says the 29-year-old singer gave birth at a New York hospital Wednesday night. Nguyen says the baby weighed 7 pounds, 8 ounces.

The father is her soon-to-be ex-husband Nas. Kelis, best known for the hit single "Milkshake," filed for divorce from the rapper in April.

His full name is Nasir Jones; baby Knight is taking his father's last name.

Nguyen says Kelis had been in labor since early Monday morning, and her mother and sister were in the hospital room.

Says Nguyen: "The beautiful baby boy and his mother are doing wonderful."
