But even though Leon — and the rest of Madonna’s children — are all growing up, the singer says being a parent hasn’t gotten any easier

“I had this funny notion that when your children get older, they learn to take care of themselves and it gets easier,” Madonna previously told PEOPLE. “But actually, the older they get, the more challenging it gets — because now they’re becoming adults, and they really need guidance.”

And Madonna is certainly not afraid to offer her guidance, even when it’s in the form of tough love.

“I’m bad-cop, I’m the one that says no,” she adds. “I accept that role. I’m not the popular parent.”
