I'm taking the comments made by his allegedly 'ex' girlfriend with a very large pinch of salt. Methinks she is enjoying her 15 minutes of fame a tad too much.
@rantanplane. No, I disagree with the use of the word 'deliberate'. That implies intent. We do not know (nor does anyone else, for that matter, at this moment in time) whether he did this with intent and full knowledge of his actions OR if he did it while affected by (a) drug side-effects (b) some physical illness, mini-stroke whatever etc.
