Busted's Matt Willis admitted he finds it hard to watch his Jonathan Ross interview from two decades ago as he was 'off his face'.
The bassist, 40, opens up about his struggles with drugs and alcohol addiction in his new BBC documentary.
Matt rose to fame in the popular 90s pop-punk band Busted with pals James Bourne and Charlie Simpson.
He discussed the pressures of getting famous when he was young, laid bare his lifelong addictions and discussed his fears of relapsing.
And now, in his new documentary Matt Willis: Fighting Addiction, he said his history with addiction has been "hard for me to watch", but hopes it reminds viewers that there are no wealth or age barriers to addiction.
In 2004, Busted appeared on Friday Night With Jonathan Ross to discuss their careers and music.
Reflecting on the interview, Matt said: "That was hardest for me to watch because I’m looking at myself and I’m 20 years old or something and I’m obviously off my face.
"It’s not rock ‘n’ roll, it wasn’t glamorous, it was really sad."
In 2005, when he was only 21, he stayed at London's Priory Hospital for three weeks to treat his alcoholism.
A year later, he was admitted again for a few days for drug abuse. He started having mental problems from the drugs including physiological and memory issues.
In June 2008, as a marriage ultimatum from his now-wife Emma Willis, he entered a rehab centre.
After getting clean for his wedding, he managed to stay clean and sober until the band reunited for a tour in 2016.
He was offered cocaine backstage during a concert and he ended up relapsing.
Matt said: "Within a month I was doing six grams, bang, bang, bang, on my own, every f****** day and not coming home until three in the morning, pretending I was working on an album, which I wasn't really writing.
"I was making... music in a studio doing coke."
In the documentary, he discussed his fears of his wife leaving him and said he feels 'grateful' that she held onto their relationship.
However, he is also scared of relapsing again.
He said: "I'm terrified of relapse. If I do that again everything will end."
