Korshunova's doorman, Mahmoud Nakeeb, 45, said the model seemed happy when she came home at about 4am on Saturday.
'She came in this morning, she smiled, no sense of depression,' he said.
'She was a very sweet girl, always smiling, never depressed-looking.'
Nakeeb said the green-eyed Korshunova was very down-to-earth, often dressed in simple trousers and shorts. He had no clue she was an international model.
