Vanessa Lachey Pregnant

Nick Lachey announced the baby news on Twitter, writing, "Can't think of a better way to celebrate 3 years of marriage to my beautiful @VanessaLachey than this! #family.”

Nick and Vanessa's son Camden John Lachey is running across the beach in the picture accompanying the tweet. Etched into the sand is a heart, inside of which reads, “It’s a girl.”

Nick and Vanessa, who married in 2011, welcomed Camden in 2012. Earlier this year, Vanessa admitted that her husband was ready to add another child to their family.

"Well, I'm not past the exhaustion point and I could go a minute with just the three of us right now,” Vanessa admitted. “But I was telling somebody earlier today that men have a biological clock. [Nick]'s like, 'Baby, I'm 40. We gotta get it moving.'"
