Singer and one-time "Newlyweds" Lachey and the ABC actress announced their engagement on Nov. 3, 2010. The couple wed on Sir Richard Branson's private Necker Island in July 2011.
Nick Lachey revealed that he and wife Vanessa (nee Minnillo) are expecting their first child.
The singer, formerly of 98° and currently serving as the host of "The Sing-Off," was appearing on "Live! with Kelly" as the guest co-host on Monday morning when he decided to share the news with the world.
Lachey said that his wife had been on the show in January. While she was in New York, Lachey was in the Bahamas. "She went to the store and got a pregnancy test and it came back positive. We're having a baby," he said on the show.
"I'm here to tell you the stage here is a very fertile place," he said.
The couple married in July 2011. Lachey said his wife is due late summer or early fall. They plan to learn the sex of the baby, and Lachey even talked about possible baby names on the show.
"If it's a girl, I think it might be Sophia. If it's a boy, I'm not sure," said Lachey, but he added that he's always favored the name Colin John Lachey. "Call him C.J. for short," he said.
