Zac Efron and Lily Collins are reportedly dating again.

The pair - who briefly dated in 2012 - have sparked rumors they have rekindled their romance after they were spotted holding hands while wandering around the grounds of Disneyland in Los Angeles yesterday. The duo were said to have been in a casual relationship last year, but split after just three months as neither of them were particularly serious about each other and they wanted to focus on their careers.

"It's true that their schedules are crazy right now, which isn't conducive to a relationship being easy," a source said previously.

The 26-year-old actor - who entered rehab earlier this year for alcohol and cocaine abuse - was spotted getting cozy with his Hairspray co-star Brittany Snow at the beginning of the month, but admitted he has been surrounding himself with women to help him forget about his troubles.
