High School Musical star Zac Efron has been forced to hire a bodyguard after he was mobbed by teenage fans on the Isle Of Man.

The 20-year-old is currently filming new movie Me And Orson Welles in the capital city of Douglas - but is being distracted by a number of raucous fans.

A 24-hour security detail is now accompanying the star wherever he goes throughout the British isle, reports British tabloid the Sunday Mirror.
