Vanessa Minnillo pregnant

Nick Lachey and his new bride Vanessa Minnillo are expecting their first child less than a year after they wed.

The ex-98 Degrees star and his TV presenter wife got married in a secret ceremony in July last year (11) and they announced on TV on Monday that Minnillo is pregnant.

Lachey tells Live! With Kelly, on which he was a guest co-host, "She was in New York and I was in the Bahamas. She went to the store and got a pregnancy test and it came back positive. We're having a baby!... This is the one thing that more than any other I've looked forward to, and it's overwhelming."

Lachey said the couple has already discussed a name for the child, adding, "If it's a girl, I think it might be Sophia. If it's a boy, I'm not sure."

He also joked his wife's baby bump was initially blamed on too many calories, saying, "It just looked like she had eaten a really big burrito for a while... She loves, she craves Mexican food right now. She could eat a burrito a day so you can imagine what our house smells like right about now."

The baby is due later this year (12).

Coincidentally, Lachey's ex-wife Jessica Simpson is also due to become a mother this year - she is expecting her first baby with fiance Eric Johnson imminently. Lachey and Simpson divorced in 2006 after four years of marriage.
