Veteran rocker Jon Bon Jovi has declared parenthood more challenging than being a rock star. The 45-year-old singer, who has been married to high school sweetheart Dorothea since 1989, is dad to a brood of four: daughter Stephanie, 14, and sons Jesse, 12, Jake, five, and Romeo, three. But he admits his role as family man has taught him how to find stability in his personal life. He says, "I'm the one with the dad voice, and if you've got to use the dad voice, I can bring it out. "I have a temper. Definitely. I'm not an angry dad. I'm not like that. But you do get your buttons pushed."
