Nick and Vanessa Lachey see pink with baby No 2

California — Nick and Vanessa Lachey are expecting their second baby, their publicists confirm.

VH1's Big Morning Buzz Live host first made the announcement on his Twitter account on Tuesday, which also marked the couple's third wedding anniversary.

He posted a photo of their almost 2-year-old son, Camden, running on the beach with a heart in the sand that says "It's a girl."

In an interview last year, 40-year-old Lachey told The Associated Press that once you have a child "everything changes, from the way you drive to the way you think to the way you act".

Vanessa Lachey, 33, who last had a role on the sitcom Dads on Fox, also re-tweeted the post.
