With barely more than a month having gone by since Vanessa and husband Nick Lachey welcomed son Camden John into the world, the happy mom is already able to show off her post-baby body – as she so fetchingly demonstrated on Wednesday.

Sporting an eye-catching patterned top and skinny jeans, the former MTV VJ, 31, grabbed a bite with some friends in Los Angeles.

Proud dad Nick, meanwhile, has already boasted that every aspect of fatherhood is a joy to him.

"That smell of your newborn baby doesn't last very long," he said, "but it's something you'll always remember. So I find myself sniffing his head and his neck. There is that baby smell that is so special, especially when it's your own baby!"
