Rocker Jon Bon Jovi has expressed distaste for celebrities who expose their children to the world's press, and he's singled out Madonna as an example of what not to do.

The LIVIN' ON A PRAYER star is proud he keeps his kids out the media eye.

He says, "She can say what she likes but Madonna takes those kids out to every premiere she ever goes to.

"These kids have done nothing and yet we all know what they look like. It's crazy, man, but each to their own.

"I've been in this industry for 22 years and no one has any idea what my four kids look like. I keep my private life private and I always have.

"My kids don't have security guards outside their school because no one knows what they look like. And that's the way I'm going to keep it."
