Los Angeles: Singer Charli XCX has revealed that she has a phobia of zombies. The “Vroom vroom” singer says she has thought about the possibility of flesh-eating monsters coming to get her so much that she has devised a survival strategy, reports femalefirst.co.uk. “I'd make sure I was in the second floor of an apartment -- then I'd cut off the stairs. I'd make sure I had enough petrol in my car. I'd stockpile raisins that type of s**t,” XCX said. “And I'd cover my mouth in case I got infected by zombie blood. You know, the simple things. I'm so good at this,” the "Break the rules" added.
