"I got a baby on the way," he told "The Breakfast Club" on Thursday, Nov. 17. "God said be fruitful and multiply. I'm doing the lord's work out here."
In early November, it was reported that the singer's off-and-on girlfriend Brittany Bell was expecting and that Nick was the father.
Us Weekly said that Brittany, a former Miss Arizona USA and Miss Universe Guam, is about six months along. The former beauty queen, 28, is Guamanian-American and has had very small roles in little-known TV shows "Good Cop Bike Cop" and "Taylor'd Problems."
Rumors originally started making the rounds because of his new single, "Baby on the Way."
Nick already has twins boys with Mariah Carey. In the same interview with the radio show, he confirmed a long-standing rumor that Mariah and him waited until they were married to have sex.
"I think we were both in that same space. I was at a point were I was being celibate at the time, and I think that's one of the ways that we bonded," he said. "The first time that we actually sat down and met it was on some spiritual stuff. Like, we were praying at all that type of stuff and I was like, 'Wow, I didn't know Mariah had that side to her.'"
He continued, "A lot of people don't know that she's a really good girl and conservative when it comes to that and deep into the bible and all of that."
