- Nick's nickname is Slider Hollywood.
- Nick is 5' 10" tall. He wears shoe sizes 10 to 10.5.
- Nick: (revealing he doesn't regret his marriage to Jessica Simpson) I think life is unexpected in a lot of ways. The best you can do is just roll with those punches and be the better person for it in the end.
- Nick: (about former father-in-law Joe Simpson) I don't pretend to understand Joe. I don't know if he ever liked me. Was he an influence in our marriage? Absolutely. There were times when I wished he would just let go a little bit.
- Nick: I was propositioned by a mother and a daughter back in 1997 when 98 Degrees were performing. In some places, the mother-daughter combination might be intriguing but not so much in Nebraska. It was kind of creepy.
- Nick: ... I'd gladly retire and hang out with the kids and clean the house. I want to have a good life and great family, and from a professional standpoint I want to be successful, but it's not the most important thing at all.
- Nick: (jokingly) I think she'd [Jessica] be the first to admit that she has ditsy moments, and it became evident very early on that it was going to be a major plotline on the show. But come on. She's not Anna Nicole Smith or anything.
- Nick: (on song writing) There's a lot of reflection that goes on whenever I write a song - it's been a wild whirlwind last couple of years and there's a lot to talk about, and hopefully that's evident in the music.
- Nick: I know it's a little hypocritical of me since I have three, but I've always enjoyed girls without tattoos.
- Nick: If I ever get used to cameramen following me around and taking video footage of me, someone shoot me, please. It's not life as I want it. You get more used to them, but to say you forget they were there, that a lie. It's impossible. There's a guy there with a camera; how can you not notice that?
- Nick: I don't feel the desire to jump back into any kinds of reality TV. The only thing I can see myself doing is some sort of The Amazing Race, challenge-driven thing.
