Zac Efron has revealed that he believes his romance with Vanessa Hudgens has worked so well because they are very private.
The High School Musical star said that he thinks they have stayed together because they keep their relationship out of the public eye.
Speaking to radio station Star 94 FM, he said: “Not much of it is public to be honest. We don’t talk about it other than the fact that it exists.”
“We just try to keep it to ourselves, which is what we take a sense of pride in because we don’t need to share that.”
Efron explained that he has become used to avoiding cameras.
He said: “During High School Musical I didn’t know how to handle it, but if you just live your life and keep doing what you do and don’t care if they take pictures, they can’t slow you down.
“I sensed a pattern – if you do keep your head down and sneak in the back entrances or whatever then they inevitably stop coming because they’re not getting what they want.”
