Ozzy's Kids Fuel Black Sabbath Reunion Rumors

God Bless Ozzy Osbourne was shown in Hollywood at a charity event for MusiCares, and while his son Jack, who filmed and produced the movie, was there, the star of the show wasn't.

Daughter Kelly Osbourne said: "My dad is doing something that is very, very exciting. But I don't know if I'm allowed to tell you. He's just finished a tour but he's doing something very exciting."

Jack said: "I can neither confirm or deny who he is with or where he is."
