The wife of Nick Lachey welcomed their son Camden John in September. "I gained, I think, 65 pounds when I was pregnant," she said. "And I will say to moms out there, 'Don't stress about losing it. It will happen when it happens.' Cam's 9 months, so it's been a minute and we're working and we're traveling and it's just about maintaining a happy, healthy lifestyle, not obsessing about it."
Lachey's secret to happiness? Spanx! "Thank you to the inventor," she added.
Meanwhile, the new mother tells US Weekly that Nick is already ready to have another child. "Right now we're happy with where we're at," she said. "We're happy with having him. But in the future, we'd love to add to our family."
