Rapper Mr. Papers is the father.
The Brooklyn-born singer stunned fans in February when she revealed her pregnancy, showing up to New York Fashion Week wearing a tight dress and an obvious baby bump.
According to UsMagazine.com, she said at the time: "I'm still going to work. I'm still going to be hardcore, the baby has made me even more of a beast!"
Lil' Kim is known for hit songs including "No Time," "Ladies Night" and a "Lady Marmalade" collaboration with Mya, P!nk and Christina Aguilera. She was good friends with the late Notorious B.I.G.
She spent a year in prison in 2005 for perjury and has been accused of having too much plastic surgery.
