Robbie Williams has hit back at his former manager Nigel Martin-Smith following allegations about his drug addiction.

The comments came in response to Boybands Forever, a BBC documentary that revisits the rise of 90s boybands, with interviews with Robbie and Martin-Smith.

In the documentary, Martin-Smith discusses Robbie’s struggles with drugs and alcohol, but downplays his own role in the group’s problems. Take to InstagramRobbie accused his former manager of shifting blame. While expressing gratitude for the success he has enjoyed under Martin-Smith’s leadership, Robbie didn’t hold back, writing: “I love you for what you’ve done for me, but I don’t didn’t like” and urging Martin-Smith to take responsibility for the group’s challenges.

“I was both terrified and excited to share a screen with you again, excited to see where we both are on this journey, and terrified, in case old emotions were triggered, and I would still be in a state of anger, hurt or fear,” Robbie wrote.

“In fact, it seems that time has done its job, and I suppose the wisdom it brings has swept away a few nooks and crannies here and there, I suppose not all the corners have been whitewashed.”

Robbie then responds to Nigel’s comments from the documentary, breaking them down and responding to each one individually. “If you follow the story closely, you can’t help but notice a pattern emerges. Boys join a boy band. The band becomes huge. Boys get sick,” Robbie continued.

“Some got lucky through a series of self-examinations and were helped to overcome their experience. Some were never quite able to untangle the mess from the rubble of the past. I am not breaking anyone’s anonymity by sharing the side effects of boy band dysphoria that only affect us guys,” he said. “Everyone publicly recorded this.

“Howard – contemplated suicide at the end of the band. Mark – addiction, alcoholism and rehab. Gas – bulimia. Me – I think this one is well documented. And Jason – whatever effect that has has had on him, it’s so painful he can’t even do it.

To Nigel’s claim in the doc that Robbie was “blaming him for taking drugs and acting like an aw****r”, the singer responded: “I would also remind you that the person acting like an aw ****r was 16 when he joined and was 21 when he left. That was the last time I saw you.

Robbie recognizes that his addiction was probably inevitable, even though he was in a boyband, and takes responsibility for his actions. He also admits that, at times, he was “mean, insensitive and nasty” to those around him in Take That.

However, Robbie expressed a desire for his former manager to show some humility, noting that Nigel had said in the documentary that he didn’t want to be seen as “a big, mean, nasty prick.”

He continued: “It’s okay to admit your flaws. No one is going to sue you for not knowing or understanding the psychological effects that everything had on everyone. We were outliers.

“Just concede a few points here and there, because no one is going to buy the version of perfection and straight behavior that is your current MO” Robbie didn’t hold back in his response, saying: “Nigel, I love you, but unfortunately it’s also true that I don’t love you,” he wrote. “The two I came to find are not mutually exclusive.”
