Obvioulsy he has never done an interview, where he has been asked about Heath's passing, and that indicates to me that he has made it an "off limits" question.
But then again, has he done ANY interviews in the past 12 months.
I guess if he has, it was to promote a new film, and as has been seen most times before, in those circumstances, they ONLY want to talk about the film they are promoting.
I have also thought too, that maybe he was caught in the crossfire when Heath and Michelle broke up, one or the other using him as a sounding board, and as happens, in such cases, there could have been some words spoken that he may regret now, and would not want to seem hypocritical, if those words were not in Heaths favour.
Who knows......I would hope that it was not that they had fallen out.
Jake seems a very deep and meaningful person, maybe he just cannot find the right words.
