Nick Lachey and wife Vanessa Lachey are ready to expand their family. The couple, who will be celebrating their son's first birthday in September, revealed they're excited to have more children, so Camden can have a sibling.

"We're always ready and want to have more kids," the Dads actress told EnStars.

But Vanessa and the 98 Degrees singer have no baby news -- yet.

"I am enjoying now. We're living in the moment, and I couldn't be happier," she said.

For now, Vanessa is enjoying her son's latest milestones, revealing that Camden "has four teeth and is a crawling machine."

"He is so determined. I see the drive in him. If he wants something, he'll go after it. It will be interesting, seeing that trait as he gets older and maybe takes it into sports, school or music. I see him having that drive to perfect things, so it'll be fun to watch," she said.

On July 25, Vanessa revealed she was getting a head start on planning Camden's first birthday.

"Operation: Camden's 1st Birthday Party is in full effect! @NickLachey & I FINALLY decided on a theme. Can't believe our boy is 1 in Sept!!!" she tweeted.

This fall, Lachey will return to TV in Fox's six-episode multi-camera comedy series Dads (produced by Seth MacFarlane) as a regular. The show centers on two successful guys in their 30s, Eli (Seth Green) and Warner (Tommy Dewey), who have their lives turned upside down when their nightmare dads (Peter Riegert, Martin Mull) unexpectedly move in with them. Lachey will play Camilla, Warner's (Dewey) wife and, the mother of their two children.
