Still, he always makes time for his kids. “I’m a tough dad, but what I realize in life is that you have to approach it with a tad bit of humor,” says Richie of his parenting style.

But when it comes to the tough conversations with Nicole, Sofia and Miles, Richie takes it all in stride.

What helps is thinking back to what he was like as a kid.

“I remember the look on my parents’ faces when I tried explaining to them that we’reThe Commodores, and we’re the Black Beatles, and we’re gonna take over the world,” he says of the singing group he joined while attending Tuskegee University.

“It’s the same look I have on my face when Nicole, Miles and Sophia come to me with their ideas,” he adds. “I kind of use that as my centering point before I completely go off.”

But more often than not, he remains calm: “I’m gonna have to kind of sit still at this point and kind of let it happen to me as it happened to my parents.”
