Nick Lachey wants more children.

The former 98 Degrees singer already has seven-month-old son Camden with his wife Vanessa but the happy couple have already discussed adding to their brood.

Nick told FOX 411: ''I think we've talked about two more but if the next one is a girl it may be tempting to just have one of each. In a perfect world we'd have a couple of boys and then finish off with a daughter. If I can orchestrate that I'd be good.''

Nick, 39, was present for Camden's birth last September and he admits seeing his son enter the world was one of the most incredible sights he's ever seen.

He added: ''I was [in the delivery room]. It was surreal but one of the coolest things to ever see in your life. You're there with the woman you love, she's giving birth to your child. It's a pretty magical thing.

''I think she went through a bit of what she calls the baby blues. I think for women you've got all the hormonal changes, the breastfeeding. It's a lot to contend with especially your first time. She's doing great though. She's a natural as a mother.''

The hunk - whose ex-wife Jessica Simpson is currently expecting her second child with fiancé Eric Johnson - credits Camden for helping ''inspire'' his new album, 'A Father's Lullaby', as it gave him a way to release all his emotions connected to being a dad.

He said: ''Obviously, [the album] was inspired by my little guy and all the feelings that came along with finding out you're pregnant and watching him being born, just a very emotional time.

''It was a great way to channel all that into music. It's either songs that I wrote or songs that are meaningful to me.''
