Currently dating his High School Musical co-star Vanessa Hudgens, Zac Efron has expressed how fearful he is at the prospect of procreating. Even though he’s reportedly ambling towards heading down the aisle with Vanessa, that’s one step he’s not ready to take.

“The very idea of kids is frightening to me. Maybe it’s over-exposure at a young age to a lot of kids,” the star has said. Efron added, “I guess you take the necessary precautions. That was the advice that was given to me early on and I’ve always followed it.”

Speaking of getting action, Zac is going to star in a big screen adaptation of Johnny Quest. The 21-year-old is hoping this will steer his career in the direction of action hero. However, Warner Bros. is considering going with a different name than the one used for the classic series. Might we suggest Johnny Shirtless? Is that wrong?
