Nick Lachey decided to celebrate his third anniversary with wife Vanessa by revealing to his fans that the couple is expecting their second child.

Lachey wrote on Twitter, "Can't think of a better way to celebrate 3 years of marriage to my beautiful @VanessaLachey than this! #family." Attached to the message is a photo of "It's a girl" drawn into the sand inside a heart and son Camden running nearby.

Nick previously told People he wanted to add a daughter to the family. "I do want a girl. I think there’s something emotional about having a daughter that I definitely want to experience. Maybe I’ll get one more boy under my belt first. I’ll need some help to keep her in line, so a couple of brothers couldn’t hurt," he told the magazine.

Nick and Vanessa married in 2011 and celebrated the birth of Camden in September of 2012. Nick has been keeping busy hosting Big Morning Buzz Live on VH1. Vanessa starred in FOX show Dads, but it was canceled after one season.
