High School Musical star Zac Efron is used to female fans getting aggressive with him but a middle-aged man is another story. According to London's Daily Mail, Efron was assaulted by a "deranged fan" as he and High School Musical co-star Vanessa Hudgens were leaving a London theater on Wednesday night. Witnesses say that the attacker lunged at Efron and pulled at his hair before being shoved away by security.
