This is the first child for the singer, and the second for ex-husband Nas, who also has a 15-year-old daughter from a previous relationship.
Kelis announced her pregnancy at the beginning of this year, before filing for divorce from Nas in late April.
The couple called it quits after four years of marriage. Since then, Kelis has filed new documents asking her estranged husband to pay spousal and child support.
TMZ is reporting that Kelis and Nas had been scheduled to appear in court today to discuss child support and pre-natal expenses.
It is not known if Nas will be in court while Kelis is giving birth.
