Rapper Lil Wayne better stock up on diapers and formula.

E! Online reports that the 26-year-old rapper welcomed the birth of his son with actress Lauren London last Wednesday.

"Lauren London and Dwayne Carter welcomed their healthy baby boy into the world on 09-09-09," a rep for the actress old E! Online. "Everyone is happy and well."

This isn't Wayne's first child, however.

Wayne already has a 9-year-old daughter from his ex-wife and childhood sweetheart Antonia Carter, as well as a 10-month old son from a mystery mama. Wayne refuses to disclose the identity of the second baby mama.

But his legacy doesn't end there. Singer Nivea, who has had an on again, off again relationship with the rapper, revealed to an Atlanta radio station that she's pregnant and it might be Wayne's.
