ET's Katie Krause caught up with the soon-to-be parents at the Los Angeles premiere of Nick’s SyFy film, Dead7, on Friday, where the Backstreet Boys singer revealed exclusively that, yes, a baby name is picked out -- but he’s keeping the moniker close to the vest.
"It's a very strong name," Nick revealed. "We can't say the name yet. I've been instructed by my wife to keep it under wraps, but we have a name."
While discussing parenthood, Nick didn't just expressed how over the moon he is about becoming a parent -- he also gushed about his wife's major influence on him.
"I don't want to get all sappy, [but] she's the reason I felt comfortable, and I knew that she would be the perfect mother," the 36-year-old singer told ET. "She would be able to help me teach our child all the things that he needs to learn."
Lauren is also looking forward to seeing Nick dive into fatherhood, noting "the unconditional love that he can give to his son and his son can give to him... and the family that he always wanted."
The pair also told ET that the nursery isn't quite done yet, but they'll have to get cracking on the room -- Lauren is due April 12!
At the Dead7 premiere, Nick opened up about another important family member -- his brother, Aaron, who's been staging a comeback as of late. The younger Carter recently released his first single in 14 years, "Fool's Gold."
"I'm extremely proud of his work," Nick said. "I had heard the song months ago when he was recording it and writing it. I think it's ironic, and at the same time fitting, that the brothers come out with two really important things at this point in our lives -- the release of my movie and the release of his single."
"I feel like we're kind of getting things together," he added. "Getting things organized. So it's nice. I'm so proud of him."
In other exciting Nick news, the singer confirmed to ET that the Backstreet Boys have signed a nine-show deal that'll soon have them hitting the Las Vegas strip. Get all the details on the mini residency below.
