Zac EfronZac Efron has revealed that he once ended up with a fake nail stuck in his back after an encounter with an over-excited fan.

The 17 again star told Hello magazine that: “I was at a premiere when a barrier broke. Fans came rushing over and grabbed me.

“The security guards stopped the commotion and no one was hurt, but later that night I found a fingernail stuck in my back. You have to have a sense of humour about it.”

He added that away from the red carpet, he tries to avoid encouraging overeager fans and attracting attention: “I make a half-a**ed attempt at disguise, but sometimes no disguise is best because, if you wear shades inside a shop, everyone thinks, ‘Who’s that?’.

“The best thing is to look normal and avoid eye contact. But I do have to sneak around and hide when I go to the supermarket. It’s ridiculous.”
