Fatherhood is already terrifying funnyman JACK BLACK - just three days after welcoming his baby son into the world. The SCHOOL OF ROCK star became a first time dad when new bride Tanya Haden gave birth on Saturday (10JUN06) and Black is already panicking about his son's welfare. He says, "I'm already having headaches like, 'Where is he going to go to pre-school? Am I gonna put cameras in every room of my house to spy on babysitters to make sure that they don't shake the baby?' "I started watching TV shows that scare me a little bit. I love video games but then yesterday I was reading about how they can be addictive and kids shouldn't play with them." But, despite his fears, the actor is convinced he'll make a great dad: "I'm gonna be the best daddy on the planet and I'm gonna enter the best daddy competition and I plan to win it."
