The Carter household is getting crowded.

Lil Wayne welcomed another child into his brood -- his second this year and fourth overall -- when singer Nivea delivered a baby boy on Monday. A source at the rapper's recording home, Universal/Motown, confirmed the birth to MTV News on Tuesday (December 1).

Wayne's Young Money cohort Mack Maine first broke the news about the birth on Monday via Twitter when he sent a message to his followers while on the way to the hospital.

"I'm currently at da hospital!!! Few minutes away from havin anutha nephew," he wrote. "Uncle Mack ya heard me ... LUV!!!!!"

Approximately an hour later, he announced the birth of Neal Carter.

"Thank god!!! Baby Neal was born healthy to Nivea Nash and Dwayne Carter!!!! Thanx 4 all the blessings n support!!!! Love ya heard me!!!"

In October, Wayne confirmed [article id="1623853"]Nivea was expecting his child[/article] after rumors swirled that the pair had reunited. In an interview with a British radio station, the Cash Money star responded in the affirmative when asked about having two women pregnant at the same time, the other being actress Lauren London, who [article id="1621375"]gave birth to Wayne's son on September 9[/article]. Wayne then added he would be having another boy.

"[I'll have] three sons," he said.

It's unclear if Nivea, who was previously married to The-Dream, and Lil Wayne are currently together. The pair dated briefly before she hooked up with The-Dream. MTV News' calls and e-mails to Nivea's camp had not been returned at press time.

The rapper welcomed his first son into the world last year, in 2008, when he [article id="1597409"]announced the news[/article] during his acceptance speech at the

2008 BET Hip-Hop Awards. His lone daughter, Reginae Carter, 10, was born to the rapper's ex-wife, Toya Carter.
