Actor/singer Jack Black has given up partying since becoming a married father-of-one. The School Of Rock star and Tenacious D rocker blames himself for giving off a rock 'n' roll image. Black says, "People stop me in the store and scream at me, 'Let's party dude! I've got pot and beer!' I never really know what to say. It's really my own fault that I give off this crazy 'let's party-and-wrestle' vibe. "I'm starting to go to bed at a reasonable hour. I have to get up and do things now. "I even quit smoking two days ago. I've been quitting on and off for the last 10 years but this time I'm going to have to quit for real."
