Nick Carter and Lauren Kitt Carter are proud new parents!
The cute couple welcomed their first child together on Tuesday, a baby boy named Odin Reign Carter, after a very long, 30-hour home water birth, according to ET.
While both Nick and Lauren managed to keep the little guy's unique name a secret throughout the pregnancy, the Backstreet Boys singer did give some insight about their baby-to-be's moniker earlier this month.
FYI: Odin is a Norse god ... and also Thor's daddy in the Marvel universe.
"It's a very strong name," the 36-year-old said at the premiere of his Syfy film, "Dead7." "We can't say the name yet. I've been instructed by my wife to keep it under wraps, but we have a name."
Nick also used the opportunity to gush about his gorgeous wife. "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," Nick confessed. "She would be able to help me teach our child all the things that he needs to learn."
