After less than a year of marriage, Nick Lachey and Vanessa Minnillo are ready for parenthood! Lachey announced Monday morning on Live With Kelly, that he and his wife are proudly expecting their first child.

In fact, if we look back to some photos of Minnillo and Lachey vacationing in Cabo San Lucas just a few days ago, we can see the emergence of a small baby bump. "She's just 12 weeks," a source told Us Weekly, the standard period of time before an expecting couple shares the news. "They're both so thrilled and so excited. They can't wait to meet the little one!"

Lachey made it clear after he married Minnillo that the couple were expecting to start a family as soon as possible. Their big news comes as Lachey's ex-wife Jessica Simpson looks as if she is about to pop while pregnant with her first child! Simpson became engaged to fiance Eric Johnson immediately after Lachey popped the question to Minnillo in 2010, although she's putting off ther wedding until after her baby is born.

Do you think Nick & Vanessa will have a boy or girl?!
