Efron winning battle with demons

Zac Efron wore a six-months sobriety chip at a basketball game.

The 'High School Musical' star, who spent time in rehab last April for alleged cocaine and alcohol abuse, was spotted wearing a blue Alcoholics Anonymous (AA) sobriety chip, given out during meetings as a symbol of encouragement and support, on a chain around his neck while cheering on the LA Lakers in Los Angeles on December 20.
