Zac Efron's alleged girlfriend Lily Collins is believed to be a good influence on the newly sober actor.
Sources revealed that the pair, who was spotted holding hands at Disneyland by fans, are "quietly dating" and added that the 24-year-old actress is the perfect girl for the 26-year-old actor as she doesn't drink or use drugs, Radar Online reported.
Sources added that the 'High School Musical' star knows that if he wants to save his career and his life, he needs to stay sober, and is making his transition a lot easier to be dating someone like the 'Abduction' star.
