NICK Lachey thinks the arrival of his unborn daughter will be a "mind-blowing moment."
The 40-year-old star, who already has son Camden, two, with wife Vanessa Lachey, can't wait for her to give birth to their second child next year.
The 'Big Morning Buzz Live' presenter said: "We're expecting a little girl, beginning of next year. I get the best of both worlds: I get a son and now I'm going to have the experience of a little daughter, which will be a completely different, mind-blowing moment for dad. On a personal side, things could not be in a better place and I could not be more excited. It's great."
The former 98 Degrees singer thinks it's "crazy" how quickly his son is growing up.
He said: "He's growing like a weed and he seems like he's changing literally by the day. "It's just a cool time. It's them finding their personality and really starting to get their vocabulary... talk in these full sentences and [you're like] 'Where did this come from?' It's just crazy."
Nick is currently working on finishing his upcoming album of covers, 'Soundtrack of My Life.'
He told UsMagazine.com: "The good thing about music is you can kind of do it whenever you find time to do it. This project actually started a few years ago... [I'm] thrilled that it's finally gonna come out on November 11. It's called 'Soundtrack of My Life' and it's a cover album -- it's all songs from movie soundtracks that were impactful to me and meaningful to me. That right song can bring out such a great moment in a film, and I really wanted to try to pay tribute to that through this album."
