POP quiz hot-shot. If you see someone standing outside a theatre waiting to catch a glimpse of their favourite star are they more likely to be either: a) a die-hard fan keen to show support to their chosen celebrity?

Or: b) akeiraweb crazed psychopath who will probably cut off the celebrirty’s head at the first available opportunity, scoop out the innards and then wear it as a scary mask around the house?

Odd-chinned starlet Keira Knightley feels the second answer is more likely after police arrested a 41-year-old man who regularly waited outside a stage door at the Comedy Theatre, where she is performing The Misanthrope.

A source tells the newspaper, “Keira felt threatened by this guy who turned up a number of times and tried to speak to her. He did not make any specific threats to her but she was concerned enough to call the police.”
