Charlize Theron 'smoked to die'

Charlize Theron has triumphed in her battle against nicotine addiction - but refuses to discuss how she quit smoking for fear of jinxing herself.

The South African beauty admits the unhealthy habit had become a deadly obsession for her and she doesn't like to open up about how she overcame the problem in case she feels the urge to light up once more.

She tells Vogue magazine, "I was highly addicted. I thought, 'I don't smoke like normal people. I smoke to die.'"
