Osbourne Suffers Stagefright
Rock offspring Jack Osbourne suffers from stagefright - despite performing daredevil stunts for a living.
The son of rock royalty, Ozzy and Sharon Osbourne, has carved a career out of pushing himself to the limit, starring in hit TV show Jack Osbourne: Adrenaline Junkie, which is now in its fourth season.
But Osbourne has a crippling secret - the thought of standing on stage in front of fans is his biggest fear.
He says, "I hate doing shows like the (awards show) Brits. My worst fear is being in front of large audiences. You wouldn't think it but I'm actually a really shy person, I get so nervous at these things."
And the star admits he forces himself to confront his fears - because he doesn't want to let down his family and friends.
He adds, "Peer pressure makes me do it and if the rest of my family are doing something, I kind of have to do it too.
"But being in front of a crowd is terrifying. Even jumping off skyscrapers isn't that scary."
