Larry Busacca/Getty Images for EJAFYou might think that Zachary, the son of Elton John and his partner, David Furnish, has it made -- growing up in the lap of luxury, wanting for nothing and having the best of everything.  But Elton says he can't stop worrying that his immense fame, which allows the boy to live such a privileged life, will also be a burden as he gets older.

Speaking to the British publication Radio *****, John says, "He's not formed enough yet to know what I do, thank God.  When he finds out, ***** look at me as if I'm bonkers.  Being the child of someone famous is a huge ball and chain around your ankles.  It's going to be very difficult."

Elton is also concerned that Zachary will be a target for bullies because he has two dads, but for right now, the boy doesn't think there's anything unusual about his family situation -- the pop-rock legend reveals that he's known as "Daddy" around the house, while David is called "Papa."

As for whether or not Zach will follow John into music, the Rocket Man says that although he wants music to be a "huge part" of the boy's life, he doesn't want to force the issue.

"I won't push Zachary into anything," says Elton.  "So far he just loves kicking a ball and watching people ****."

In that same Radio ***** interview, John -- shocker! -- says something nice about Madonna.  According to the U.K. Press Association, he gives the dance diva credit for being a pioneer for women in music, saying, "Madonna took the industry by the scruff of the neck, made opportunities for other women, like [Lady] Gaga and Katy Perry."  

That's certainly a departure from his recent comments on Australian TV that Madonna looks like "a fairground stripper" and that her career is "over."
