The thing I like the best, especially being a parent of so many kids, Is that they're all so different. You love them all equally, but they're all so different from each other and that's the cool thing, to see their personalities start to develop and see how unique and different they all are and to be able to love them in their own unique ways. It's really, really, really special.

I tell people, Don't take my advice. What do I know?

Throw in the towel right off the bat. Women argue in ways that aren't rational to men.

You have to imagine - for those who are good dancers, maybe they don't have to train as much - but for me at least, not being a very good dancer you have to hit the reset button every week and come in on Tuesday, the day after the live show, and start all over and learn a whole new dance with a whole new set of emphasis. Some weeks, you want to have body doing one thing. The next week, it's a totally different thing. You always have to relearn everything on a weekly basis and it takes a lot of work mentally and physically.

We live in a bizarre world - there are cameras in our house!

To me, having kids is the ultimate job in life. I want to be most successful at being a good father.

As long as there are teenage girls, there will be boy bands. It's a question of how long it takes them to get their music together to come out.
