The artist confirmed that he was about to be a father of three during an interview with The Breakfast Club in November.
"Who said it wasn't mine?" Nick replied when asked about Brittany's pregnancy. "I've got a baby on the way … absolutely ... God said be fruitful and multiply. I'm doing the lord's work out here."
Rumors that he was expecting a little bundle of joy surfaced in early November. Brittany, a former beauty queen, is believed to be seven months along.
Coincidentally, Nick has a new single out titled, "Baby on the Way."
In a chat with Entertainment Tonight, Nick said of his impending third child, "It's outstanding. Honestly, they say even in unexpected situations, you still embrace the beauty of bringing a life into this world, because that is what life is all about."
Brittany has taken to Instagram of late to show off her growing baby bump.
Last month she posted an image of her holding her small bump. "💛 'Children are a gift from God...' Psalm 127:3," she said.
She later shared another image of her wearing a shirt featuring gum balls where her belly was protruding.
"Life growing inside you is fun during the holidays.. people ask what I/we dressed up as .. well.. here you go 💋 #gumballmachine #bubble," she said.
Before Nick confirmed the baby was his, the former Miss Arizona USA and Miss Universe Guam shared a snap with other beauty queens, most of whom were touching her belly.
"A sweet moment of #celebration with a few of the many incredible women in my life. Missing the rest of you 👑👑👑👑👑," she wrote. "Miss USA /Miss Universe not only puts you in a rare sisterhood no money can buy.. but your child ends up with some of the most naturally beautiful, sweetest, and strongest women from around the country/world to call Aunties!!💛 👑 #misscaliforniausa#misswyomingusa #missarizonausa #missusa."
