Robbie Williams never blamed his former manager for his drug-taking and personal problems during his early years in Take That.
The pop star has written an open letter to music mogul Nigel Martin-Smith - who brought the boyband together and managed them during their 1990s heyday - after they both appeared in new BBC documentary series 'Boybands Forever' and Nigel seemingly suggested Robbie blamed him for his troubles - but the singer has insisted his substance abuse issues would have happened even if he was working as a "taxi driver".
