The star recently opened up to PEOPLE about fatherhood and how his children are his biggest fans when it comes to his music.

"I know my kids love my music. I don't know about any other entertainers and their kids, but my kids actually dig my music," he said. "They're actually the best people to get critiques on my music from because they're not listening to it the way music people listen to music; they're listening to whether they feel it or don't. That's very useful to me, so normally I'll run a song by them, and if they like it, I know I'm going in the right direction."

"They're very quick to tell me how much they don't like something — just as quick as they tell me how much they do," NE-YO added with a laugh.
