The 'Mirrors' hitmaker - who has son Silas Randall, 13 months, with wife Jessica Biel - knows it is tricky that his son has grown up living in the spotlight but says the "best thing" he can do is help him understand what fame is and what it means.

He told The Today Show: "He's 13 months old right now, but you think about the next five years and the next five years after that, and you think about the fact that he just got here. He hasn't made any choices. He chooses eggs or bananas.

"You think a lot about the lives that me and my wife lead, but I wonder what privacy's going to mean in 20 years. Those are the questions that enter my mind, for sure, but I think that's something that you don't have control over.

"The best thing I can do is to try every day to give your kid perspective so they understand what it means and what it doesn't mean."

Meanwhile, the 35-year-old singer previously revealed he loves changing his son's nappy.

He shared: "Oh, you look at everything differently now! Yes, having a little man in the house now changes everything!

"When I used to clean up my dog's poop, it was like it was a science project; I wouldn't get very close to it. When you have a kid, and there's poop, you gotta get in there! Nothing trumps your kid's butt cleanliness. So you just have to get in there!"

And Jessica is equally loving being a parent to the little boy.

She gushed: "He's wonderful. He's just a joy. It's an amazing, amazing experience.

"[It's] incredibly hard, the hardest job in the world and I've never been more thankful and grateful to my own mother. Oh, my gosh I'm going to call her right after this actually and just thank her. What you have to do for your kid -- it's an amazing responsibility and the biggest joy ever."
