Pop sensation Justin Bieber has reportedly said no to drink and drugs. "There's no one just looks up to more than Carl. He's had a huge influence on him. They spoke at length about how he can get his life and career back on track and both agreed that getting rid of alcohol and drugs was the natural first step. "Justin has made promises like this before but this time we all genuinely believe he is clean. His manager Scooter Braun was very clear that, until Justin sorted himself out, his music comeback was on hold," a source said.
