Vanessa and Nick Lachey might have a nine-month-old boy but they are already eager to add to their brood.

Apparently the couple, who welcomed son Camden last September, had planned to have their children “back-to-back”.

The couple are parents to a nine-month-old son called Camden. 

A source told Life & Style magazine: “Vanessa always wanted to be a mom, so she is loving it. She said she wanted more babies right away and to have them back-to-back.”

Nick has also previously spoken of his hopes of more children: “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.”

Vanessa has shared a number of pictures of her family on Twitter. 

However the insider added that the pair, who tied the knot in 2011 five years after they got together, won’t be rushing into anything just yet.

“They definitely want to have more babies, just maybe not as fast as they originally planned,” they explained.
