And now the proud papa has revealed why they called their son Camden John.
"It's kind of a funny story," Nick told People. "I've always like the name Colin. We thought that Colin would be the name. And John is my dad's name."
"But as we got further into it, I learned that Vanessa wasn't a big fan of the name Colin, so we started looking for another 'C' name."
Vanessa's doctor's office is on Camden Drive in Los Angeles and one day he said, "Hey, what about Camden?"
"We didn't really know anyone else named Camden. It was such a neat name. We fell in love with it and decided on it five or six months ago," he shared. "He's not named after the city in New Jersey."
Other new celebrity parent Kristin Cavallari has also called her new baby boy Camden.
The 38-year-old TV host has fallen head over heels with his son and is growing as a new dad.
"As a first time parent, you don't know what to expect," Nick shared. "You get all that advice, but we've been blown away and happy about the fact that he's just been a good baby. He's got a great temperament. Every day is fun. It's a new adventure and we're loving every second of it."
Nick shows off his son in an adorable picture for Tide's photo sweepstakes where football fans share images of their proudest moment wearing their team colors - in Nick's case the Cincinnati Bengals.
