Vanessa Lachey Gained 65 Pounds During Pregnancy

The “Wipeout” hostess and wife of singer Nick Lachey explained, "I gained, I think, 65 pounds when I was pregnant. And I will say to moms out there, 'Don't stress about losing it. It will happen when it happens.'”

She added, “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."

Vanessa advised fellow moms to avoid fad diets too. "It's not about this 'get skinny quick' diet or these fads. Just enjoy time being a mom. You've just had this wonderful, magical moment, and you shouldn't be stressing about that kind of stuff."

Of course, "Spanx are amazing," she joked. "Thank you to the inventor of that."
