Zac Efron was once left stunned after a fan literally sunk her claws into him - and left a fingernail embedded in his skin.

The High School Musical heart-throb is regularly besieged by crowds of screaming girls at red carpet events. And he'll never forget the day a very enthusiastic female admirer managed to catch hold of him - and refused to let go until she had left a reminder of herself behind.

He tells Britain's Hello magazine, "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 humor about it."

Now, the actor has learned the best way to avoid causing hysteria is to simply be himself. He adds: "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."
