Nick Lachey and his wife Vanessa named their baby son Camden after the road in Los Angeles where their doctor's office was based.
The couple welcomed Camden John Lachey on 12 September (12), and the singer has now revealed the reasoning behind the tot's unusual moniker - he is named after a street in Beverly Hills.
Lachey admits the couple initially wanted to call the baby Colin, but Vanessa went off the idea, so they found inspiration after visiting her obstetrician's office on Camden Drive.
The singer tells People.com, "It's kind of a funny story. I've always liked 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... (After visiting the doctor, I 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's not named after the city in New Jersey."
